I'd like to see a Kid Icarus for Wii U, but I kinda hope they don't feel like they need Sakurai and his team to do it.
For one thing, he's tied up in Smash next, which we probably won't see until 2014. So the next Kid Icarus would be like 2016 at the earliest. I don't wanna have to wait until 2016! For another thing, I'd like to see what other games Sakurai has in his head when he's not tied down with a sequel to something. He gave us Kirby, Smash, Kid Icarus, and Meteos. What else does he have up there?
I think he did the hard work and laid the groundwork for what future Kid Icarus games should be. So they can get another team to follow that and add to it on the Wii U. Maybe have Sakurai offer input, even if he's not directly overseeing the game.
Treasure would be a pretty good fit, but I feel like they'd need help on all the story and writing parts. They don't do story much, and when they do, it's pretty awful. See Sin & Punishment. God, those were some painful cutscenes. The story and characters and writing are a big part of the charm in Kid Icarus, so whoever does the next one, they really need to make sure they nail that part.
Really though, I just want to play this game with the Wiimote. Stylus controls are fine, but Wiimote would be so good.
