I find so much wrong here.
For one you really don't seem familiar with Wine, which despite being run by a ragtag group of developers already has brought legacy support for most Windows games on Linux.
The bluray argument is largely moot.
Valve and the game industry at large could care less about it, with consoles as the exception.
Gabe and his team only have to present a console with an advantage over existing consoles (modular build is a huge deal) with a distro that is stable. With the impressive bases already in existence, and OpenGL being a fullfledged match for Direct X it's a no-brainer that Valve has what it takes to pull this off.
Lastly I'd like to point out the Linux community is not uniformly against closed source. What makes our veins pop is stuff like hardware OEMs not releasing driver sources, making development and innovation a pain.
Who cares if a game is closed source?
I think you're right about Wine. For games Circa 2003 and earlier I often have much better luck with Wine than I do on a modern Windows install if I'm using original media.
Not to mention that every game I've ever gotten from GoG has worked pretty smoothly (IE close to effortlessly) with Wine. I've only run into trouble with stuff like installing 3rd party infinity engine mods.
I think in some ways Linux is a better platform than Windows for retroclassic games.
Most interesting about Wine (to me) is its use as a pre-packaged porting mechanism; I've seen a few indie games whose "Linux port" is just the Windows binary and a wrapper script that opens that binary with Wine and the correct DLLs.
