There's going to be ALOT of people in this thread pretty embarassed with what they've said in this thread when it comes to ODST. Anyone who thinks this game isn't going to be massive is crazy. Its Halo FPS and its going to be budget priced. You do the math.
In terms of sales then no there is no game on the ps3 that stands a chance of outselling ODST this holiday season unless GT5 is released. Halo FPS are the Xbox's bread and butter. Quality is a whole different argument though.
