Yeah... he said the same about Super Mario 64 (whole system got delayed) and Super Mario Galaxy (Iwata: "I'm pushing Miyamoto-san to release it right at the launch of the Wii!")
With pretty much one big game a month starting June and Mario Kart plus Animal Crossing AND a 3D Mario for the holidays things would look quite crowded, wouldn't they?
They are probably planning for a Mario Bros. to be released late next year so I guess this one will be an early 2012 release - as in "Q1-early" since they seem to be using assets from Mario Galaxy which means less development time.
Jeez, why are they so afraid of "milking" 2D Mario? It's probably the most milking-resisting game series in the market =/
