You may not be aware but LEGO take submissions on what they should make for new sets. If they get enough votes it goes through to LEGO for approval. Not all of them get approved, but when they do it can lead to something wonderful.
Case in point. A Back to the Future DeLorean complete with Marty and Doc has been approved.
How cool is that? It will be out at some point next year.
The video below shows the kit and a few others that may be heading our way.
