Looks like it's going to be an expensive Christmas this year.

Xbox 360:

Halo 3 (Legendary Edition)

Mass Effect

Ace Combat 6

Call of Duty 4

BioShock

Assassin's Creed (maybe)

PC:

Crysis

World in Conflict

Enemy Territory: Quake Wars

Hellgate: London

Left 4 Dead

Jeez, I have no clue what's coming out after that. Then again, I can only afford about 1/3 of the games on this list. :(
