The only reason Microsoft is making a these acquisitions is because their portfolio of studios was piss poor compared to Sony to begin with. This notion some people have since E3 that Sony is suddenly in some huge amount of trouble is laughable.
I didn't mention that they are in trouble, just that MS is preparing to hit hard on next gen and Sony dosn't seem to be making efforts to counter it. One of the biggest advantage of Sony was his first party strength, they should keep that as an advantage instead of being mostly iddle on that front.
