I think that New Super Mario Bros. 2 will be massive. People at my work were talking about video games the other day, and four or five of the seven that were there (not including me), all massive "HARDKOR 4EVERZ" type gamers are buying 3DS' with NSMB2, they said that it looked innovative and appealed to their competitive natures, if Nintendo can pull in that crowd, as well as bringing back the casuals, it could be as big or bigger than the original. Whilst I'm here, I may as well make a few lifetime sales predictions :P
NSMB2- 28,500,000
SM3DL- 16,250,000
MK7- 22,750,000
KI:U- 4,500,000
Inevitable Pokemon Game- 24,570,000
MH3G- 6,500,000
MH4- 10,000,000
Pokemon Rumble Blast- 3,000,000
Paper Mario: Sticker Star- 5,750,000
Luigi's Mansion: Dark Moon- 5,100,000
I'll predict the 3DS' lifetime sales as being around 135 million, based on Mario+Pokemon+3rd Parties. It will be huge, no doubt, but I don't think it will be as big as DS is/was.
