The problem with 5G
Here's my problem witrh the 5G as a dream picture: unless I'm wrong, it'll take a lot of energy to move 60 fps from the cloud to a smartphone and controler data from the smartphone to the cloud with minimal latency. Thus destroying autonomy.
This will seriously limit the appeal, at least on the go. And in a fixed environment, fiber-based wi-fi will probably be much cheaper.
And it's pretty much the same with all the other "5G is not an evolution scenarii" such as automated driving coordination, telemedicine and whatnot.
BTW the console lifecycle is still 5 years.
