Toy Story 4?

So my wife and daughter were playing Nintendo Wii today, and they had an interesting idea for an upcoming Toy Story installment:

They suggested that they need to update the toys in Toy Story to include some of the new virtual toys...like the "Mii" characters you create on the Wii. Of course those characters would only appear on a TV screen, but they would be able to interact with Woody and the gang.

I took the concept a step further by suggesting it could be a hybrid of Toy Story and Tron, where some of the Toy Story gang end up having an adventure inside the game?

Come on guys...what do you think? Disney owns both properties. It's perfect!

Here's the pitch:
The film opens with Woody and Buzz playing a Wii (or similar) version of Star Command. They create their 'Mii" avatars, which (because this is Toy Story), come to life inside the game!

Cut to: INSIDE THE GAME. Woody and buzz discover that Emperor Zurg is about to hatch his latest diabolical plan: if your Mii dies...you die! Can this be true? Can Woody and Buzz somehow manage to get a message out to their their real world counterparts...before it's too late!?!?

Come on on guys, who's with me?

Oh, and just in case any of the good folks at Pixar are interested in this idea, it's for sale! Unless of course they're already doing it.
