I'm one of them...

Your loss.  I really love the art style of game.  I don't mind realism though but I still don't see what you don't like about the art style.

I think it should do well.
It's a well known franchise.
It's coming out later than the pack and the week it releases it won't be competing for retail space with 3 others kick ass games releasing the same week.
It's different enough from the other games already released these holydays that it will not be competing head to head with any of them.

While it is a well known franchise unlike assassin's creed was last year, this particular PoP game isn't nearly as hyped as assassin's creed was last year. For that reason I really don't know what to expect from this game sales wise.
