We're probably not getting hoverboards in 2015, bt at least we have the consolation of knowing that Lego approved an actual, licensed Back to the Future DeLorean set for release in the middle of next year. The set - which should include the necessarily Legos to modify the DeLorean for all three movies, as well as various figures of Marty McFly and Doc Brown - was submitted to Lego's Cuusoo site, where it reached the necessary 10,000 votes to be considered and was chosen by Lego for actual production. What's super-cool is that Masashi and Team BTTF, the people who designed and submitted the set, are donating all of the royalties they'd receive from the set's sales directly to the Michael J. Fox Foundation to help fight Parkinson's disease.
Apparently the next judging period includes a Portal 2 set. Cross your fingers.
