A 3DS Brain Age game would definitely make sense for Nintendo. The series hasn't seen a new iteration in a while and is an almost definite 10 million seller.
With Nintendogs for launch, Brain age during summer and Mario Kart / Animal Crossing for Christmas the 3DS will see four 10 million sellers in its first year on the market.
We'll also get Zelda ( a potential 5 million seller) Professor Layton, Resident Evil, Metal Gear Solid, Kid Icarus, Pilotwings, Paper Mario and Bomberman, which will most certainly sell a million copies each.
And for 2012 we can expect Pokemon and Super Mario Bros. to sell in excess of 10 million copies.
I don't think there has ever been a videogaming console with a comparable number of hardware moving software in its first year. And we're still 3 months away from launch!
