Lets take GTA as an example. HUGE sales numbers, cross platform. Comes out every 3-5 years building anticipation. Do you really believe in 2018 that this will be released for the amazon kindle fire box or whatever its called?
Maybe it will get a port of GTA4 by then, maybe. Im sure Rockstar is hard at work on GTA6 for Ouya and Amazon 
Farther in the future you may be right but not in this gen's consoles lifecycle. These android tv boxes are for streaming media and kids to play angry birds or minecraft. If nothing else people are extremely loyal to the xbox and playstation brand. No ones looking for amazon unless they really change the game.
