Recently lego announced a new theme called "Lego Mixels." It is going to have it's own Cartoon Network show as well as some sets.
What exactly it is, we don't precisely know apart from what has been posted on the lego wiki (which we still don't precisely know.. it's a wiki, what can you expect.) It will feature "the colorful Mixels creatures that can mix and combine with one another in creative and unpredictable storylines. A collectible portfolio of low-priced mini building sets will launch in three waves in 2014 and an app-powered gaming experience will engage fans in a deep mobile game that will cover the sprawling world of Mixels."
It is one of those things that may have promise, but could also be incredibly anticlimactic. The fact that lego is working with cartoon network is certainly not promising imho (I personally find the Chima and Ninjago TV series to be some of the worst media decisions by Lego). However this about an "app-powered gaming experience will engage fans in a deep mobile game that will cover the sprawling world of Mixels" could be really cool, maybe even like Bionicle. Remember, Bionicle started out small. It might also be like the old creator x-pods which were pretty cool.
But it's all in the balance. Though this theme is geared for a younger audience, I hope there will be a deeper storyline that could appeal to us older fans.
