Yups, it has been confirmed, January 29th through February 12th for all platforms.

The Open beta will be located for download and installation on the Xbox Demo section of Xbox Live. You will need an Xbox Live gold subscription in order to participate. Simply download and install as with any other game/demo.

This is an Open Beta which means most areas of the game are near complete, however we are still looking at balance and polish. Feedback is always welcome.

seems pretty late though even it is an open beta , can't complain though aye least we can get a practice in AW YEA

inb4all the big flaws are in the release version rather than in the beta

Now it should be worth waiting.

Hmm same time period as C2? Does that mean I'll like the beta more than the retail game?
