Why would valve do that? they already have a machine of their own.
It would be them admitting defeat if they had to go to Samsung and ask them for input in how to design a console.
Also philosophies would probably differ.
Valve would want to make a new steam machine, much like the old one, basically just sell people a pc.
Samsung would probably want a real console, instead.
*Edit:
I think the most likely of those options you can vote for, is Google makeing a android console, for your TV.
Would have a app store, app system, run all android games, and have unique games developed for it, it would have gens like current hardware consoles do, so game developers know what to aim for ect.
I could see google actually trying and probably makeing it work.
