Source 2: free and open source!

Wouldn't that be a great move? Not sure how they would make the money on it then, but I think it would quickly beat most other engines out there in popularity.

I don't know if that's Valve even wants, but it could be if say that would get most game developers out there to create OpenGL/Linux-compatible games by default, and since Source 2 will only support OpenGL (I think), that could be one way to do it.

Valve has stated they want to bring the community closer together for buying/selling/trading of goods. I would expect they would make their money that way.

I doubt they would dump DirectX completely. They've reworked the engine for linux to not care if it's running DirectX or OpenGL. Leaving this intact could provide a way to eventually port to Android/iOS and other mobile platforms? Valve has stated they want to get into the mobile space but have seemed to fail thus far. I recall them mentioning Linux was a natural step to go from Win Desktop -> Mac -> Linux to Mobile running Linux (Android)

At least one Valve game will be running on Android soon, Portal is coming for the Nvidia Shield in the next few days:

It looks like Nvidia is handling the port themselves, though, so who knows what that means for other Valve titles.

EDIT: Well, apparently Half-Life 2 is getting ported next. So Valve games are coming to Android, although only for Nvidia Shield users so far.

They would make money if Source 2 was designed to make Linux a premier development and gaming environment. Valve wants everyone on Linux, eventually. It's the only refuge they have from the walled garden lockdown future of Windows.
