Said this before, and I am going to tell it again. If MS does not manage to get their shit together next-gen, the Xbox brand is good as dead and will follow Nokia and Windows (for mobile) into the grave. No amount of second-rate studio purchase will mend the damage that was done in the past 7-8 years.
Nokia is rebounding pretty well now - though outside of the Microsoft ecosystem, of course.
