Well, that will be a really stupid idea...
If MS were to be going full-on third party then that "may" be great. On another note, if steam were owned by MS from day one and has grown to what it is now, MS would not even need an Xbox platform. This ting is simple.
While MS has Windows, MS is making zero $$ from game software sales (not published by MS) on the PC. Games sold through steam or other PC game stores. As it stands Xbox has gone from being a direct game console rival to Playstation (which lets not kid ourselves is what it was always intended to be) to becoming this gateway platform for the MS gaming ecosystem.
If the Xbox were as successful as the Playstation, the majority of the initiatives MS is taking today wouldn't even be on the cards. They just wouldn't need it.
MS needs to focus on one thing... and win it. Make one area heir own and build on that. Cause right now, they sure as hell seems like a jack of all trades and master of none.
More importantly, though Halo is already coming to PC, if MS intends to build out their presence on PC they simply can't do to their PC initiatives what they have already done to their Xbox console initiative and release their gateway games on a nintendo platform.
