Aparently, Aliens: CM has been delayed because a new chapter in the Alien vs Predator franchise is the priority now:
" While this is very good news, it comes with a small dose of bad. The new Aliens vs. Predator will be the first title released as part of Sega's Aliens franchise, meaning that the eagerly anticipated Aliens: Colonial Marines isn't going to make its original 2009 launch"
Damn this thing to hell! Aliens Colonial Marines is the game I want to play! I don't really care much about the Alien vs Pred thing... :(
Actually since AvP2 on PC is one of my favorite games of all time this isn't such bad news. Though they had better not rush the thing an make it crap. And it had better be an FPS not some goofy action game or rpg.
