I'd also like to point out, it is quite possible that Galaxy 1 sales were somewhat interrupted by that of Super Smash Bros Brawl and Mario Kart Wii. I mean games on the same platform compete (even if with evergreen Nintendo titles where it doesn't seem to exist). Meaning Galaxy could have sold much more had it not been for Mario starring in two more games within 6 months after its release. They go to the shelves to find a game and they want the latest Mario game and well that would have been Mario Kart Wii or Smash Bros Brawl to a lesser extent. Personally I think Ninty should have spread the releases out more but oh well.
So if we kinda take Galaxy 2 in the same context, it may not have to deal with that same competition and potentially get more sales because of it. I still expect Galaxy 2 to release November 2010 so we'll see how that goes.
