LEGO Ideas has just announced the results of the Third 2014 LEGO Ideas Review Stage and the next project to become an official set is the Labyrinth Marble Maze by JKBrickworks. As a result, it is the first board game type project to become an official set. As a kid, I remember playing with the original wooden Labyrinth game and this brings back tons of memories. Soon a new generation of kids with get to enjoy this classic game as well.
LEGO is also still considering the Star Citizen F7A Hornet so we could again potentially see two sets becoming official sets from this review stage. As you can see, there were many projects that were worthy of becoming an official LEGO set but alas there could only be one winner (maybe two).
The First 2015 LEGO Review Stage is currently going on and the results of those projects (shown below) are expected to be announced this fall. Around that same time period, more details of The Big bang Theory, Doctor Who, and WALL•E sets will be revealed as well.
