Walmart has listed down MAG 2 under the video games department of their website. It's set for a 2011 release. Interesting, very interesting.
Zipper Interactive themselves have not announced any plans for a sequel to the massive FPS game that is MAG, they're currently working on Socom 4, so take this news with a very large bowl of salt until then.
MAG offers online battles that are 256 players strong and a unique ranking ladder. The on-going beta is testing out a number of features currently, including Move support.
