A new Assassin's Creed mobile game will launch in December of this year for English and Japanese audiences. The title is being developed by Ubisoft and GREE. In the same breath, GREE is teaming up with Gameloft on Gang Domination, which will be available on various smartphone devices this coming June.

So, what's GREE? Beyond being a company with way too much money, it's a mobile publisher/platform that's huge in Japan and is moving into the global marketplace, launching the GREE Platform in the second quarter of 2012. The company bought mobile social network OpenFeint last year and has offices in Tokyo, San Francisco, London, Beijing, Sao Paulo and Dubai. The company states: "GREE will continue to aggressively expand worldwide."

"GREE will continue to focus on building relationships with third party game developers and publishers as it moves towards releasing its new platform."

So, if GREE wasn't on your radar before, it appears to be a company you're going to be hearing about a lot in the near future.
