Honestly, I don't doubt the technical feasibility of an Android console, but they just don't seem to be catching on.
I was one of the "early adopters" that bought an Ouya. I figured I would mostly use it for XBMC anyways and the games would just be a bonus. Thankfully XBMC works OK as the games never really materialized there (the Final Fantasy ports are about the only thing decent available).
I also bought a FireTV - again, mostly as a video device (Netflix, Hulu) for the living room TV. Again - the games haven't really taken off. The Telltale games are available on it (but then again they're available almost everywhere) and I did see SW: Knights of the Old Republic was made available for it, but overall its pretty stale.
Personally, I'm not going to be rushing out for this one until it proves itself to not be another flop. The only thing that MIGHT would interest me would be the ability to stream games from a PC, but all the steaming options I've seen in the past recommend a wireless or "robust" Wifi connection, which I generally interpret to mean it'll suck over WIFI.
