"The next stage is where things really get exciting"
I don't see anything to be excited about. The whole Game as a Service thing doesn't work, not every game HAS to be a "multiplayer experience"; they don't need to realize "DLC drip feed" to bleed the customers one dollar at a time. It may generate revenue in the short term, but it doesn't seem sustainable.
Remember Simcity 2013? EA is trying to force this GaaS concept ever since (if my memory doesn't fault me). It didn't work then, it doesn't work now and it probably won't work ever. Stop turning single player games into MMOs by applying Frankensteinian methods, gutting parts to make them DLCs, adding stuff to make them ever online and so on.
