Assassins Creed 2 if you have played number 1 and you enjoy creation of humans and conspiracy theories or Heavy Rain if you want a relatively slow game that is extremely engaging.
Dead Space 2 was exactly like Dead Space 1 with a different skin and the multiplayer was nothing to talk about.
Haven't played Just Cause 2 but I would suggest Deus Ex as it was pretty good but it all depends on what you're into.
If you can wait, I'd wait for Skyrim. You will get quite a bit of play time and if Morrowind and Oblivion are anything to go by, it will be good.
