Microsoft for sure. They just wanted to stop Sony from conquering the living room and they're not passionate about gaming like Sony are.
Sony is buying and creating developers for long term, for decades into the future, while MS is investing in motion controls and third party timed exclusives which is a short term strategy.
Also, historically Microsoft from his investors has demands to achieve almost unrealistic profit margins of 20-30% that just aren't possible in the gaming business long term. While Sony's shareholders accept a more realistic 0-5% profit margin.
I sincerely hope I am wrong though.
