And we have yet another new 2013 LEGO theme that will be replacing an old one. Last one was Legends of Chima replacing Ninjago, this one is Galaxy Squad 2013 and will be replacing Alien Conquest. Seriously LEGO, just wait a year before replacing a theme. You've done it before, and you can do it again.
But it is coming out. And you most likely want to know the set list. So here you go:
70700 Space Swarmer
70701 Swarm Interceptor
70702 Warp Stinger
70703 Space Mantis
70704 Vermin Vaporizer
70705 Bug Obliterator
Sounds like humans vs space bugs. And it sounds very similar to the popular CUUSOO project Space Marines.
