Unfortunately I'd expect that.
The WuuPad likely does no processing, so it's probably only one frame behind say 16-33ms.
Most TV's are >50ms of latency and it's not uncommon to be in the 100ms range.
It's the same reason that when you use OnLive or Gaikai and compare it to a console experience on a TV it has similar latency.

But wouldn't most people use OnLive or Gaikai on their TV in the end^^ Then it's worse, unless they manage to reduce the games inherent latency... which is unlikely, unless they use massively fast hardware to overcome this problem.
And a "good" TV usually has a Game Mode, or at least lets you really disable all the unneeded postprocessing. Mine does. But it's also still slower than my PC LCD.

For us luddites,is this good news?
It's not that it works so well, it's that TV's suck so badly.
Pre HD TV's most tube sets had 0 additional latency.
Now you have a fantastic TV if that number is < 33ms.
It really does impact the quality of control in games, but people get used to it.
Yes it's a contrived example, but one that was broadly publicized to demonstrate that cloud based gaming was practical.
As I understand it Gaikai uses very powerful machines and runs games at 120Hz to minimize the latency from the game itself.
Even in "Game" modes on "good" TV's it's not unusual to see latencies in the 30-60ms range.
But this is getting off topic.
I guess it is good news, Power7 is a powerful and modern cpu family...

Which seemingly, Wii U does not have, thus ruling it out...
What do you base that statement on ?
The various rumors that Wii U is having CPU issues, holding it back in regards to PS3-360 ports.
It seems if you're struggling to match lowly (these days, very lowly) Xenon, well, speaks for itself.
Of course, worth noting, there is a running sub-theory amongst Wii U defenders that the Wii U CPU isn't actually inferior to PS3-360 CPU, just different, and thus ports struggle. But there seems to be an excuse for everything with that crowd. And again, matching PS360 would be nothing to write home about, and would not qualify as "modern and powerful".

I've been expecting WiiU to be like Wii--basically something that would have been pretty good this-gen, and dated next-gen. And I expect developers to react the same way--when the next-gen consoles come out, we will suddenly learn that first person shooters, RPGs, and all other kinds of games that we've been seeing for the last few years are positively impossible on such ancient hardware, and it's most definitely impossible to render graphics in a realistic style rather than some bizarre "artsy" thing.
IBM have to play the PR game same as everyone else. They aren't going to say, "it's a limited core severely cutdown from our flagship chips, that can perform similar to last-gen consoles," if that's what's actually in the box. Whatever they put in their will be dressed up as prettily as they can when they talk about it. Whereas devs making games aren't going to be deliberately trying to gimp the CPU. If WiiU's struggling in games then there's not much under the hood. And we don't have to go just by internet rumours as we can actually see games that are starting to be shown, plus a history of gaming rumours tells us that plenty of anonymous dev comments turn out to be true.
If the option is to believe a half dozen anonymous sources (and sometimes named developers) reporting to gaming websites that the CPU isn't all that great, and one comment from a business that has to maintain positive PR at all times, I'd place my faith with the anonymous sources in this case. I don't see how a full-fledged Power7 would struggle with the code that Xenon is working on - it should be able to mince Xenon in typical computing.
I'm not calling it either way, but I agree with Ranger's thinking.
But can they say "it is Power7" and be lying? wtf!
For one it's a marketing twitter account
And second, it could still have a lot of the power7 ISA implemented without being a Power7 chip.
My guess is that the WiiU chip may use eDram for the cache (L2, not L3 like the actual Power7 chips) and implements some of the VSX vector instructions that came with Power7. I doubt it has 4 way SMT threading or many of the other functional units that aren't needed in an embedded processor.
