1: If one of those four should miss the game, I'd bet on Eggman or Tails. But it might be a curveball.1: I've already got the next Smash Roster decided and all but 1 of those characters are in it. (It's more like two really. The third is added as DLC.)
2: I already have a Dinosaur Planet sequel planned, but it's not until late 2010s.
3: I was thinking of Pixar doing a Nintendo movie. (I was considering Pikmin mostly because IOTL Miyamoto made the Pikmin Shorts. Plus I really like Bug's Life and would love to see Pixar do another movie from that kind of perspective with more modern tech.) But Pixar is more the type to come up with their own movies than adapting an existing property. Although if it does happen then we'd be delaying (and potentially killing) whatever Pixar Movie was happening around the time. You suggested Cars but that might bee a bit too early for me. Nintendo is protective of their IPs so I want them to start small in terms of licensing IPs out. (Starting with a Metroid Comic by Archie.) Although I'm not against Nintendo thrusting into a movie deal this early in the timeline.
2: Well, now that Rare is part of Nintendo, and with Retro Studios being defunct, they have a lot of monkey business to attend to, if you know what I mean...
3: Fine. You've made your point. In fact, if Pixar does do a Nintendo movie, would we see Amiibo be referenced in any Toy Story project after the creation of that line?
