I've heard rumours that it will be called The Lego Movie 2: Duplonian Invasion and will feature bad guys and good guys from various franchises that they own (Darth Vader and Voldemort being a buddy cop duo is one of the things revealed) but still retaining the fire original characters like Benny, Astro Kitty, and Wildstyle.
Woody has a lego figure so they should add him in the lego movie 2, I could totally imagine woddy just running upt to emmet and his friends somewhere in the movie and he just scream at them "YOU. ARE. A. TOY!"
