I agree, some of those are pretty questionable decisions. I think they should have been able to come up with something better than just closing some of those studios. I mainly question what they did with Ensemble, although I do have issues with them closing down FASA as well. Hopefully, Weisman will release a decent Battletech/Mechwarrior game with the license they acquired from Microsoft.
If Lionhead is releasing Fable II for the PC, Microsoft is still in the PC market; although it is a lot smaller of a presence.
