So here is what we know about Star Wars: Visions...well there's really not much to tell you yet. Starwars.com provides a glimpse at a couple pieces of artwork from Abrams Books and Donato Giancola that will be included in the book slated for a fall 2010 release. A book with various interesting takes on visions from the Star Wars universe by a number of talented artists? Sounds like as good a guess as any to me. We'll be sure to keep you posted.
