I doubt NSMBW will be able to sell more then Galaxy 2 over the next twelve months for simple reasons. Firstly NewSuperMarioBros:Ds has only sold 21-million units and has a much larger console base to buy the game. I doubt that NewSuperMarioBros:Wii can ship that many units this next year.
So that means less then 7-million units for NSMBW. I also suspect that Galaxy 2 will outperform Galaxy one at least during the launch year. So I'm betting NSMBW will ship another 3-4 million units this next year which is really high but one thing Nintendo has proven is Mario has legs. But I suspect about 6-million for Galaxy 2.
So in the end I think Galaxy 2 will beat NSMBW this year from a few days ago on. I am so confident I doubled my last bet (Which I lost) double or nothing with Pyro. But to be honest I was 70% confident when I made the first bet but am 90% confident making this one.
If NSMBW does actually outsell Galaxy 2 during its launch year then wow I suck! Then again I predicted WiiFitPlus and everyone laughed at me.
