Speaking of parks, remember how Iwata also stated that they would be more opportunistic in licensing their IP out.
Imagine all those parks out there that aren't Six flags (WB) or Disney, that are dying to find something more marketable than random stuffed animals and Peanuts characters like Charlie Brown.
Think of all the marketing Nintendo will instantly have nation wide. From kids walking around with Mario & Luigi hats, bowser shell backpacks, koopa and gooma pillow pets, princess Peach and Zelda dresses, Link Swords, DK Ties, Giant Yoshi & Kirby Bean bag pets, a much better arcade (Mario Kart 4 player, F-Zero, DK, SMB, etc etc), Characters walking around taking pictures and giving autographs. Re-themed kids areas and rides. So much money and marketing that Nintendo has been ignoring for decades while letting Peanuts stay relevant by default.
So instead of waiting for Disney to buy them out, they could make moves to be increase product awareness without them.
