Gaming always has a shiny object that it chases after and tries to convince everyone that its the next big thing.
We saw alot of success with the Wii mote but that only lasted a few years and the other companies motion controls never came close to taking off like that, Microsoft told us that the cloud was going to make the Xbox One 4x more powerful than the native hardware would normally allow, they stopped talking about it after the system launched, then companies told us how VR is finally ready for the mainstream and its going to change everything when the writing was on the wall that its still a long ways off from being ideal for the average gaming fan, now we have companies tell us how big of a deal game streaming is when nobody asked for it or seems enthusiastic about the game streaming services we've had for years.
Once game streaming launches and inevitably under performs they'll go chase the next shiny thing that nobody is asking for.
