Remember that Tim said the Doom3 is scalable, and I bet they're holding a lot back because the engine will push mid and lower end machines too much. Once 2gig geforce4 machines become standard, say end of next year, I'll bet they release an add-on pack or something. And of course, I pretty sure map makers are gonna go sick with this game, and co-op, well, after messing around with the Omaha Beach MOH:AA mod, and seeing how much it messes with the sripted sequences, I'm not holding my breath for co-op. Then again, OpFlash did co-op almost flawlessly...
