Does MS have an IP that on level with Gears or Halo that we don't know about?

i think they will go back to the black tusk ip once gears is out

Dude...Gears of War will most likely not be out until 2017. The preliminary work for Gears is still underway. If MS focused on multiple IP's with Black Tusk that would be a new move by MS. MS is known for keeping their studios focused on one game whom have a heavy hitter.
