It seems Microsoft might be launching an all-new IP. The company has filed a trademark on “Adera.” The mark filed with the USPTO states that it’s to be used for “game software,” namely an “online computer game.”
Aside from that, there’s no other info given. Right now we don’t know if this is for an all-new XBLA game, a Kinect game or whatnot – heck, it might even be for the company’s next-gen console for all we know.
Expect more details as it develops.
