Ouya and Gamestick are low-end
Shield, Steambox and Wii U are mid-end
X720 and PS4 are high-end
I'm somewhat interested in a steambox. I'd like a duel-boot with android (Google TV). I'm hoping for a 4 year lifecycle with every two years a new iteration. I'm also interested in Oculus Rift. I'll be waiting how things pan out, but steambox is on my radar. Not buying anything for at least 2 years.
