If you don't know what 'Impostor' is, it's a new system developed at Bungie that substitutes highly detailed models for simpler ones when they're seen at a distance. In short, that Jackal taking pot-shots at you from up on the top of that Covenant sentry platform has way less good looks than the Grunts that you just wasted right in front of you- only you never notice the difference. And if you were to approach said sniper? The engine would scale him up to look appropriatly more awesome the closer that you get. Nice stuff.If this truly is the max level of graphical quality for the 360 though, I have to wonder how far away a neXtBox could truly be. Might we see something announced at e3? Maybe something incorporating the Natal tech natively? It certainly is possible, but I doubt that Microsoft would want to temper any excitement whatsoever for the impending 'Holiday 2010' launch of the Natal with a new console- even if it were to be a ways off.
E3 2011 though? I'd be shocked if there wasn't something being cooked up for that.
