its all about resolution. the HD abe screenshots are 720p and the xbox ones are SD which could be 420p. so the SD ones are scaled up to fit over the HD pictures.
This is a pretty standard way to show the progression from SD to HD. i could of scalled down the HD pictures. but it would be harder to see the diffrences and it would give the HD pictures extra anti-aliasing.
if you were to play SW xbox on a hd tv, it would blow the pixels up like this and maybe even add a blur filter over the top. really go check! same for any old game.
poor halo 2 oh how you don't look as good as I remember
