I think so, too.
Look at Bungie, they were pretty much Halo only. Sure they made games before but none of them was as big as Halo and that was their baby for more than 10 years now.
The problem is that it takes bungie 3 years to do a full Halo game and you will only see two of them in one generation. I can understand their need to do something different, but I can see the MS need for another Halo. If Bungie wanted to make another game, MS would not have a Halo for 5 or 6 years. That is too long and would hurt the franchise.
It is the same situation for Polyphony digital and Sony btw. Imagine PD focusing on a totally different project than GT. This would mean no full GT till 2013.
Therfore I like studios like Naughty Dog, Remedy, Insomniac, Rare or Epic Games.
I hope that Lionhead will do something diffrent than Fable tbh. Fable is one of my favourite franchises ever and I love everything about it. So Lionhead is one of the best developers out there IMO. But after 3 awesome Fable games I think they should do something different like a survival game (don't know why I picked this one, I just think they would be good at it) and release it in 2012 and comeback with Fable IV in 2014 on a new machine.
Just my 2 cents.
Imagine not having GamePass on your console...
