The actual outcome will be that there will be pretty minimal ramifications. Stadia will basically fill the gap for those not necessarily wanting to upgrade secondary or work hardware for gaming, which will be pretty small market. Mac Users, Laptop users and potentially IT, what’s left of call center employees will be enticed by the discreet in browser conduit for gaming.
Android users playing across a multitude of Android forks that make it impossible for developers to code one game to run on all phones will have a solution. Whether consumers will buy into it is a separate matter considering light, casual and FREE games with MT are what sell in high quantities on mobile with only a few exceptions and that’s the opposite of what Stadia is proposing.
There aren’t a significant number of existing console or PC gamers with any interest in game streaming that also have monster internet connection that will want to take advantage of it.
The fact is most gamers already got a huge sour spoonful of insane greed from more than a few game publishers (especially EA) and rejected it. The result of rejecting a whole slew of full priced but still Pay2Win games has the majority of the existing community extremely reserved to downright defiant of any shift the seeds more control to game publishers.
Moreover, in the US atleast, with Net Neutrality being a thing of the past even if game streaming were to become significant it wouldn’t be long before Google would be continually extorted for more cash or face crippling random “throttle out” states from ISPs and those additional escalating costs would be passed on the the consumers and that would be above and beyond whatever other psychologically manipulative gambling mechanisms they would attempt to employ.
