After a Excellent Smash Bros and Kid Icarus looking great what should they do next?

Smash Bros 3DS most likely.

Starfox.

Personally after seeing the campaign of Brawl I really want to see them create a platformer. The first thing that came to mind was a DKC reboot but Retro did that since. A Kirby game wouldn't be half bad either but that to is being done. I think they should launch a new IP or maybe reboot Ice Climbers or something.

Of course others point out SmashBros. They did do a great job and I would love to see another SmashBros title. But I think Hal could handle that. Or maybe Nintendo EAD. I'd like to see Sora bringing something fresh to Nintendo. A new IP or another reboot.

Then again I want to see Retro creating new IP too. I think that newer studios should create new games. Then again I wouldn't mind some reboots. StarFox would also be pretty good if they did a good job with Kid Icarus sky battles then I would love to see them bring Fox back.

Also I hope Sora's next game is a home console game , next generation obviously.

I would love for Sakurai to try his hand at a new IP.  I want to be surprised by it, which means I have little idea what I want it to be

Marry Riku and hang up his keyblade.

A new IP

Smash for wii2 and 3DS... But actually a new Ip wouldnt be bad at all... 

He did say he was considering Star Fox to reboot before the idea of Kid Icarus came up.  But he chose Icarus because it had been forgotten.  I wouldn't mind seeing him do a Star Fox title.  What I like about this guy is that he has a way with simple game mechanics that shine in Kirby and Smash, and seem to be noticeable in Icarus as well.

Kill Goofy.
