I definitely see this as a trend, but I genuinely hope it doesn't become one. Cloud gaming is yet another step in the slow erosion of our ability to actually own stuff, and would be bad for everything from selling games to making mods to video game preservation.
It's disheartening how many people don't see the dangers in only being able to access media/software at the whim of a large corporation who can shut said access off at any time for any reason.
I'm unsure on this one; cloud gaming has been around for 10 years and little to no progress has been made on the technical issues in that time i.e. compression artifacts, latency, lack of support from developers/publishers.
