A new Fable game with MMO elements would be cool.
Also, some new IP's wouldn't go a miss.
Kameo was really good for a launch title, so clearly Rare still have it within themselves, but hopefully they can get the support from Microsoft.
They've been lost after Fable 3 with silly Kinect rubbish and messing about with the 360 avatars.
Time for them to get back on track.
