The speculation was true. Crysis Warhead looks like it will indeed be the next game from Crytek.
The official Crysis homepage has updated itself with a new splash screen, showing the, well, bemused look of Crysis NPC Psycho, weilding a gun and apparently staring at my left foot. So let the speculation enter Phase Two.
After Crytek's peculiar outburst during which they blamed piracy for their impressive sales (or something, I got confused), it seems pretty unlikely this will be a PC exclusive. But surely they'll not entirely abandon the PC? Console-only Crysis games have been rumoured. Of course there's no way of being sure just yet. Also, what's up with Psycho appearing in the pic, and not the previous masked figure?
Edit: C&VG are saying they've heard that Psycho is replacing the previous protagonist.
