They didn't cover other IP's because they didn't dig deep enough. Redmond is working on something and Rare has 2 Core IP's in the works. One is a shooter and one is an action/adventure games.
Rare - 2 Core IP's
Black Tusk - 1 Core IP
Lionhead - 2 Core IP's
Then you have Ryse and Alan Wake 2
That is 6 (one of Lionheads game is a Fable game) games we know about that is different than their typical games.
