Pimps at Sea (Halo 3) spotted on Xbox Live; new 360 theme announced

A handful of Halo 3 fans spotted a few users playing "Pimps at Sea" on Xbox Live last night. For those who wern't aware, Pimps at Sea is common codename that Bungie uses to refer to the Halo 3, and it was a big part of their April Fool's joke. Bungie gives the details in this week's update:

There was a very special Pimps at Sea Humpday last night, the first night in which players were able to take each other on in the Alpha. One of the playlists that’s being tested in matchmaking right now is Rumble Pit, which is the same as Halo 2’s except it’s set to four players right now. Last night a very special match occurred with some special participants.

Bungie also announced that a Xbox 360 Dashboard Theme based on the new TV ad will be released in the near future.
