There's some backlash in Europe and Australia apparently over 4G / LTE support, as apparently it isn't compatible with frequencies over there, and so it has had to be removed from marketing campaigns as basically the feature might as well not exist. Clumsy!
Yea, the "new" iPad ( stupid name ) uses 700Mhz en 2100MHz, but in the EU, we use 800Mhz, 1800Mhz and 2,6GHhz. In other words, the LTE option is totally incompatible. But its advertised as a Wifi + 4G.
So people think when they buy it, they have 4G support in Europe. Not going to happen it seems.
There really need to be a universal standard for these things. Even in the US, you got way to much differences between even 3G setups.

Do they actually advertise LTE support in Europe or only mention 4G? Originally even LTE wasn't considered 4G. The same decision that allowed LTE to be called 4G also allowed HSPA+ to be called 4G legitimizing T-Mobile and AT&T in the States for example referring to their HSPA+ networks as 4G. Apple actually distinguishes between HSPA+ and LTE by displaying the 4G symbol when connected to HPSA+/DC-HSDPA networks and the LTE symbol when connected to LTE networks. If Apple only mentions 4G and not LTE support in Europe then they are technically correct.
There are no LTE networks up in Europe yet?
By the time there are, I'm sure they will support the requisite bands over there.
News this morning is about them issuing a dividend and stock buyback. In all that talk, they said 2/3 of the $100 billion cash they have is overseas, so sales outside the US is obviously a huge part of their business.

There already are LTE networks in Europe, some are still at 'beta' stage and some are final but it's not like iPad will have to wait for Europe to catch up. On the contrary, Europe is ready for LTE devices but apple made the wrong call with designing their new iPad with only US market in mind.

Is DC-HSDPA much more common in Europe? I hadn't actually heard of DC-HSDPA until the iPad 3 announcement and Apple mentioned in in reference to Europe. If LTE is more common in the US than Europe and DC-HSDPA is common in Europe, the networks they chose for the iPad 3 are consistent with Apple's usual policies on not adopting cellular standards until they are fairly widespread and can be done without sacrificing battery life. Being used to 7 Mbit/s HSDPA myself, I would think the performance distinction between 7 Mbit/s HSDPA and 42 Mbit/s DC-HSDPA would be enough to not be too concerned about lack of 72 Mbit/s LTE. Although I can see how it's annoying to have a feature widely advertised in North America not available elsewhere.

That could explain the situation, although it is still not nice what they have done. Would prefer to have an option of using LTE where available, and not have LTE which is unusable in my region.
There are LTE projects going on, but nothing is commercially available. The problem is not that LTE is not available yet, but it seems that the bands are on different frequencies in Europe, and require a different antenna / chip, whatever in the "new" iPad.
Its not like they are magically going to start selling those bands that the iPad uses, just for the iPad's users. You have the same problem with phone's. A phone needs to support 800/900 range, if you want to use it both in the US & EU. If it has only one, its locked out in the rest of the world.
Think that China is also using the same range as the EU?
There's some talk that the LTE networks in the US would be challenged by iPad supporting LTE -- and even more with the next iPhone.
I wonder about the pricing of LTE in other countries because in the US, it's a joke. Fast speeds but low caps means you really can't use it much before hitting the cap.
Hopefully popular LTE devices force carriers to change their pricing for LTE. May force them to upgrade their networks and backhaul to truly support LTE.
When FaceTime came out, people were pointing out that other countries had video calling for a long time. That may be true but the pricing made it so that people weren't using it very much. We talk about the capabilities of the device to encode/decode 1080p video with increasing bitrates but the mobile infrastructure makes all those capabilities somewhat moot.

More than likely, by the time LTE networks are available over there, there will be new devices out.
We get lots of overheating iPhone 4s at work at well, so that wouldn't be too surprising ...
Not really, we have beefed up 3G, which we call 4G. Right now it is around 40Mbit/sec and will be upgraded to 82Mbit/sec by year end.
We use 2600 Mhz, 1800 Mhz and 800 Mhz in Europe.
That sounds like DC-HSPA, which the iPad is suppose to support.
I recall Vodaphone Italia advertising that for some cities but not all of them.
So if A6 is presumably on 32 nm, can we expect the power consumption to decrease, resulting in a smaller battery next year? Or would A15 and Rogue cores just eat up all the efficiency gains fro the die shrink?

I think the consumption from the display overshadows that of the app processor, so I don't think it'll matter much on the iPad. However, assuming Apple uses an A15 configuration, that would eat up most of the power savings from moving to 32nm by itself.
If Apple goes custom ARMv7, perhaps they could have a three core CPU set-up to fit each of the main workload profiles: a core of roughly A15 level performance when processing demands are intensive, another of roughly ARM11 performance to handle most active tasks, and a core of roughly ARM7 performance to run idle or standby necessary workloads. All three cores could run together or shut off independently, and they should all be compatible in order to make the hardware balancing as transparent as possible to the developer.

You'd be surprised. A typical 1280x800 panel consumes roughly ~700mW-1W depending on the image being displayed. The iPad3's may be significantly higher, but still on the order of ~2W. That's well within shooting distance for an apps processor if it's heavily GPU loaded. I'd imagine the A5X goes well past that to ~2W when loading all 4 543's.
Honestly, the only reason why 4G is being so strongly pushed in the US is because Verizon's 3G network caps off at around 3.1Mbps. Investing any further in EvDO back in 2008-2010 with the EvDO Rev. B standard when it was clear that LTE was the future would have been a dumb idea. The rest of the world has HSPA+ networks which can scale up to 84Mbps should a carrier have enough spectrum, which is plenty fast in the downlink.
