JoBlo has a bit of information about TOY STORY 3, some of which is gleaned from comments made by John Lassater during a recent animation thingie overseas. Timothy Dalton will voice Mr. Pricklepants in TS3; his character is described as being "a thespian hedgehog toy". Apparently, an as-yet-unreleased trailer for the film has provided more insight to what the movie's actually about. We've already heard many indications that TOY STORY 3 would carry something of an emotional charge (a la the first thirty minutes of UP) - the holocuastic plot described below supports this notion.

SPOILERS!!!

plot details were revealed at the conference that I certainly hadn’t heard thus far. Supposedly the catalyst to set things in motion is that the toys are thrown away by Andy’s mom after he heads off to college, and eventually they end up at a day care center where they’re abused by toddlers. They must band together (with some new toys, thespian hedgehogs presumably included) to figure out a way escape, and hopefully find a new (or old) owner.

...says JoBlo HERE, where you can find a few more details. TOY STORY 3 is scheduled to hit theaters next Summer, after a 3-D re-release of the first two films (starting later this year).
