Well, the problem with your theory is Microsoft give out scholarships and rewards for up and coming developers. They are also happy to educate someone for free. They have been doing this for years.
Plus, as someone else pointed out, they sell only 1/3 as well on Sony. It would be nice to see Sony work to help bring new games, so we would all benefit from more talent working in the field.
So, it seems you are referring to the wrong console. But I don't think Indie's are what sells systems anyway.
Indies are like the candy at the Cinema (Console). Yea, it's fun and enjoyable, but you are really going there the feature film (Big exclusives.)
