I don't think it's going to be a runaway success, more of a "Rome wasn't built in a day" situation. It could create a a viable PC gaming alternative for the living room. I don't think initially this will be as compelling an option for most people compared to the consoles, but if they keep applying pressure with it, year after year, it could really disrupt things (which would be good for everyone). Pushing Linux gaming in an environment that has been dominantly Windows for decades is no small task. I think Steamboxes have a ton of potential, but it's likely going to take a long time to hit it.I think with the release of the steambox and controllers, valve will be competing very hard with the console market. If it is widely adopted, I could see games getting even cheaper. Iinstead of having to port from pc to console and vice versa, steambox games will be the same as steam games on pc unlike xbone and ps4 to pc and vice versa. And the ability to constantly upgrade your console and run mods will be a huge plus too. Mark my words, steambox will be a huge deal once it is fully released.
