There have been quite a few news regarding the first party support for Microsoft Xbox 360 console lately and I can't think of anything not positive. Some people said MS had the weakest first party support, but the best 3rd party support of the big three.
The investments Microsoft made are really big so that a new look at the Microsoft studios is worth it. So let's go:
Lionhead Studios
Currently working on Fable: The Journey

There is still the MGS Mobile studio, which produces games for Windows phone 7 and XBLA (Ilomilo) and Xbox Live Productions, which created South Park Tower Defense play.
I think with 5 new studios in 6 months MS made it obvious that they are heavily investing in their first party lineup. MS Victoria should be a team of 60 employees, which is quite a number.
The people working at 343 industries are basically a bunch of the top developers in the world. RARE just hired 5-6 new people coming from all over the world and with different industry background.
Lionhead is working on another title beside Fable.
If MS keeps up their awesome 3rd party support and the 2nd party partnerships with Epic, Remedy and Crytek they offer the total package. All the new stuidos and new staff will be ready for next gen. Give them a year or two to build everything from the ground up and you are fine. 2013 should be perfect for them.
I am quite amazed by the growth in the past 6 months. Maybe they buy another studio next year as well. Remedy, Frontier or even Epic Games were rumored.
Imagine not having GamePass on your console...
