Firstly, I've found some awesome pictures courtesy of The Pixar Times' Pixart section (almost as good as the Buzz in the Grid picture from a while back): firstly is this awesome picture from Mark Crilley, entitled the Increditoys (pretty self explanatory);
Fluffy Friends, and features Bonnie from Toy Story 3 meeting Boo from Monsters, Inc., it is from Andry “Shango” Rajoelina, I encourage you to check out his blog, if not just for more picture like the 2 below (left from Pixart), with the right mashing up Pixar's Ratatouille and DreamWorks' How to Train Your Dragon.
Now, we have also seen a great video, which, to put it simply, is what Up would look like if Disney made a live action version in the '60s. Who thinks these things up?
Also, in terms of articles and updates, we have been told (courtesy of Disney, etc.), that DreamWorks' upcoming animated film, Rise of the Guardians, based on the upcoming books by William Joyce, will star the voices of Chris Pine, Hugh Jackman, Jude Law, Alec Baldwin, and Isla Fisher. As well as being executive produced by Guillermo Del Toro. More details here.
