As most users know, Steam Box is a console that allows to play most Steam games. It works the same as an XBOX (CONSOLE not HOME COMPUTER).
GamePop is a service announced for 2016 that allows to play [Android (APK), iPhone/iPad/iOS (ipa)] mobile games on a PC. It is a virtualization software that *comes* with a console & game controller for ~ 200 $. There is also a subscription of 90 $ yearly associated with the *service*.
Will there will be an unique platform in the future ?
(Mobile, Console, PC merged)
To my knowledge, I can play XBOX *APPS* on PC with win10.
XBOX merged with Windows AppStore:http://www.theguardian.com/technology/2016/mar/01/microsoft-to-unify-pc-and-xbox-one-platforms-ending-fixed-console-hardware
With online platforms as Steam / GOG.com, you can usually buy a product and play it MAC/Windows without paying extra. Those platforms give you the right binaries for you. :3
Will game industry *shrink* in the near future ? I assume most people buy 2x AAA games per year. The lifespan of games increased. Minecraft and Skyrim Mods are an example of that. Games have more content (mods, dlcs, expansions) and are harder/longer to *beat*. Eventually, AAA games will come out less often to optimize the sales. I spend most of my gaming time on browsers games and old games. On a big note, I will never own GTAV. QUAKE LIVE best FPS.
