Most Likely:
Rock Band

Possibles:
Orange Box
COD 4
Assassin's Creed
NFS:Pro Street

Have to reserve some money for Wii games...

Mass Effect is a definate.

My maybes are the Simpsons Game, AC6, Orange Box, CoD4, and Assassin's Creed. I may also pick up PGR4 and a couple of others I cant remember. In the end it all comes down to time and financial constraints.

What's the prediction on Mass Effect sales?
It looks like everyone here is buying it.

Assassins Creed
Mass Effect
off the top of my head, heck i could go crazy and get other games but those are for sures.

Mass Effect,COD4,Assassins Creed

Mass effect, ace combat 6, virtua fighter 5, assassins creed.. few other potentials for 360.

Mass Effect, Assassins Creed, Ace Combat 6.
Mass Effect will easily sell around a half a million on its first week of its release.

More than likely, I'll end up with all of these: * means maybe

Guitar Hero III
*Rock Band
Call of Duty 4
Mass Effect
Ace Combat 6
Clive Barker Jericho
