It's the open space for discussing what the next-gen consoles will be (not technicals), looking at business choices and competition. Competition with PCs strikes me as a valid part of that. If the next-gen consoles are fairly middle spec'd, they will encounter much stiffer competition. My own assumption was at release, the new consoles would provide better value than a middle-of-the-road PC, but that might not be the case, at which point the value proposition of these machines need to be reexamined.
This is a discussion that I find amusing, in part because I read other PC-centric forums that continually bash consoles for "holding back" PC gaming and giving them nothing but ports.
Unless my memory is mistaken, when the 360 launched it was the most powerful gaming platform you could buy. It was competing against single core P4s for the most part. The launch of the 360 (and then the PS3) moved gaming into the multi-core arena. But 360 only held that crown for about a year.
About a year or so after the 360 launched, Intel came out with their Core2 processors (or, at least those became "standard"), which were a huge jump from the P4 era, and then halfway through this console cycle we saw Intel make another HUGE leap with the Core i series of chips that really just wiped the floor with everything else in terms of performance. But how long were PC gamers stuck using P4s with "hyper-threading" that no gaming software took advantage of?
Is it possible, now, for MS or Sony to launch a console in 2013 that beats only the most expensive of crossfire/sli, quad and eight core systems?
I think it's possible, and I think for the consoles to survive they MUST. They must, as Shifty has said, be able to be clearly superior to any mid-range PC you could pick up off the shelf. Otherwise, they are going to have a very difficult time.
HTPCs aren't uncommon these days. If I recall correctly, the original 360 didn't even launch with an HDMI port. Now, everything has an HDMI port, including tablets and cellphones. Almost any device can be easily plugged into any fairly new TV.
For the PS420 to succeed, they most certainly need to be more powerful than the core i5 I've got hooked up to my TV that I use as an HTPC that I bought for $300. And that's where the customization needs to come in. Adding eDRAM or increasing the memory bandwith, something needs to be custom designed in order to facilitate a better experience, even if the CPU/GPU are on par with their contemporary mid-level PC counterparts.
So I'm still hoping for the PS420 to launch as the best gaming experience outside of thousand dollar custom built PCs. I don't know how long they will be able to hold that crown (especially as it doesn't seem like Intel is facing the same sort of pressure these days as they were from AMD back at the 36 launch).
