Nice but I don't really give a shit anyway. At 3 meters from my television, at 30-60 fps I for one won't see much difference between 720p and 1080p, and if you're really concentrating on the gameplay you shouldn't even have time to really notice. Also, like some posters already noted: remember that 1080p rendering takes 4x more pixel crunching power, and this has to come from *somewhere*. Think less multitexturing, simpler vertex & pixel shaders etc. This will make games look crappier than they do now, *especially* on 1080p...
I agree with the guy before: damn Sony for hyping up the 1080p bullshit so far that MS gave in to it. This is like choosing quantity over quality, just to be able to bad-mouth and yell at each other...

. It's especially sad knowing that the PS3 will have mostly 720p games as well, seeing that it has a weaker GPU than the 360.
BTW, playing HDTV / 1080p is a different subject, 1080p is great for that...
