Well the 360 doesn't have to hold the entire frame in the frame buffer at the same time. It can write it as tiles one at a time, I think it takes 2 tiles at 720p with 4xAA.
Halo 3 did render at 640P, but didn't it render TWO 640p frames and combine them and then stretch them to 720P?
I'll wait for the Eurogame anaysis before I pass judgement on KZ2. I'm curious what their video capture hardware shows.
Yet, today, America's leaders are reenacting every folly that brought these great powers [Russia, Germany, and Japan] to ruin -- from arrogance and hubris, to assertions of global hegemony, to imperial overstretch, to trumpeting new 'crusades,' to handing out war guarantees to regions and countries where Americans have never fought before. We are piling up the kind of commitments that produced the greatest disasters of the twentieth century.
