So it's an iTouch/iPhone game due in spring. *yawn*
Nothing offical , Kojima says to wait a few more weeks.

The next Metal Gear game will be shown soon...whatever it is.
At the Spike TV Video Game Awards this past weekend, we had a brief moment to speak with Hideo Kojima as he walked down the red carpet. Obviously, the big thing on our minds was the next Metal Gear game that he recently teased. Not surprisingly, he didn't reveal anything new at all, but he did say that it's just a matter of weeks until we find out what it is. Given the timing -- a few weeks happens to be around the start of the new year -- this could indicate some sort of exclusivity window has expired on Metal Gear Solid 4, meaning an Xbox 360 version could then be announced (which was one of the common assumptions from the tease, given that its letters were all green). Or, the timing has little significance and it just happens to be when he'll reveal a Metal Gear Game for iPhone or DSi (another common assumption thanks to the "i" in the tease message). Either way, we'll know soon enough.
Kojima also indicated that he is indeed working on the new project he recently referred to while he oversees the next Metal Gear games. Sadly, it's not another Zone of Enders. Here's the video of our brief chat
So it could be as they said , exclusive time frame is done at the start of next year
