I have been saying for a while, and hoping even longer, that their next MMO will be based on the canned Starcraft: Ghost. Something like Planetside(never played but aware of it) or one of the other FPS-MMORPGs that failed to deliver. There's a huge player base of "twitch-gamers" gamers out there playing FPS games for free, and it is something they could bring to consoles to capitalize on the Halo crowd if the controls are simple enough.
