To let everyone know, Rare didn't go to Microsoft, Nintendo sold it to them because Rare games weren't making profit. As of right now, microsoft is having a hard time with them. Just think about it from a busniess point of view. Four years and the parent company (Microsft now/nintendo past) keep on paying the employees and development cost of games that are only release at the end of the system life cycle. By then, even if the game sells well the money it makes won't cover cost of development.
