They mentioned a lot of games that definitely will have sequels. There will be a Civ VI but Civ V is still fairly new. The Vegas games were awful tactical shooters. The gunplay itself felt great, but the AI, squad commands, map design, cover system, weapon balance, and controls (no lean feature?) were all awful. Battlefield will continue. Burnout Paradise basically did with NFS: Hot Pursuit.
I would love a new Homeworld, Star/Earthsiege, a F2P UT 2k4, GRID, Freelancer, Xwing vs TIE Fighter. A lot of sci-fi there....
