I think this game will probably sell 3-4 million at least, and over 5 million is feasible. Anything less than 2 million will be a flop, imo.
However, I also believe that this game will have very nice legs given the type of game it is, and it may take quite some time to get to these numbers (2+ years to reach 5 million, if it does).
But yeah, anything less than 2 million in a few years would be a flop at this point, imo, especially now that we know it's going to be bundled in some territories immediately upon release. I always figured this game would be bundled at some point (it's the perfect game for it), but I figured it wouldn't happen until at least a few months after the fact, like MotorStorm.
As for "huge", I'd say that really strong sales (5+ mil.) plus a well known brand are a good indicator of success. I believe this game's sales will be limited somewhat by install base and demographics, but that a LOT of people will know about it that don't own a ps3, and thus haven't bought the game. If Sackboy really does become some sort of mascot for Sony, than it would be considered huge.
