At first when I heard this, I thought that my brains would explode from laughter. However, after I recovered some oxygen, I thought that he could be right.
Now you are probably thinking that I am crazy right. Well if you look at the numbers, there is still much more Nintendo Wii out there than any other console. Of course I don't expect everyone that have Wii to buy this game, but if you think about it, what’s the upcoming "good" titles for the Wii this holiday season? There is Lego Indiana Jones (If you like that kind of crap), Tony Hawk Ride (If you got a wallet full cash, and medical insurance), Resident Evil Dark Side Chronicles (If you like games where you can't move) and finally there's Modern Warfare Reflex (which I have no idea what it looks like).
Chances are that most people are going to be buying New Mario Bros for two reasons, first one being lack of good titles to spend money on, second being everybody fucking loves Mario (and Yoshi, but not you Luigi).
Therefore, if you think about it it is not impossible for NSMB to outsell MW2 on the PS3. However, it is not something I would put my money on. What do you think? Is it going to outsell? Is Reggie on drugs? Am I on drugs (Yes BTW).
If you missed GameTrailers TV, you can still watch it over at Gametrailers.
