The new stuff is hopefully in my post, and if my math is right (and his video is right too), the game has pretty much exact same delay interval as other 30FPS games tested in that article, Halo 3 among them. So I don't know if there's something really different about it (doesn't feel like that to me at least) or it's just people overanalyzing the game again.
Compared to CoD4, this game, being 30FPS *will* have more input delay, as CoD4 is a 60FPS game, and such games have half the number of frame delay. Maybe that's how the whole hoopla started with, but there's probably nothing that can be done about it.
