So Microsoft is watching VALVe's Steam Machine plans with "Great Interest"

I see lots of good stuff coming out of this competition is good.
Here are things I think might happen in the next few months and the next few years from Microsoft due to competition.
1. Microsoft might step up their game dramatically on Windows and make it even more developer friendly for video game developers to develop video games on and sell them on.
2. Microsoft might try to push advancing DirectX even more than it has before so OpenGL ends up being behind it. I am pretty sure Microsoft has the cash to spend on research and development (R&D). Nvidia spends $1 billion dollars (USD) or $10 billion dollars (USD) on research and development (R&D) of computer graphics I don't know which one is true cause the translation got messed up so if someone finds the actuall cost please post it in a comment.
3. Microsoft might actually end up releasing DirectX as a full open source graphics API due to Linux, SteamOS, OpenGL, and AMD's new API Mantle being competition or as I said in #2 advance DirectX to a great new height possibly release DirectX 12 in 2015 or DirectX 12 before next year ends?
So what do you think? Comment away.
