Starcraft 2: Legacy of the Void still won't be out.
Neither will Half Life 3.

Does it matter really what the future for PC gaming is?
PC Gaming folks tend to think of themselves as this unique playing platform that somehow magically isolated from other platform for gaming. Which it isn't. Consoles, PC's, and mobile devices gaming are all same darn things, just viewed a little bit differently.
The big thing, I would say with PC gaming, is Transgaming. Being able to take your games with you, via mobile devices, and/or have causal browser/app games that effect the PC game. A lot more interconnectivity between causal and general gaming, and it's probably going to get more apped focus.
I think we're going to see the MMO market, be virtually dead with only a few standout games.
I think we're going to be seeing a higher number of microtransactions, and DLC, allowing us to pay for the part of the game we like, allowing us to pay a lot more for the games that we really like.
I think we're going to be seeing AAA titles be released for free, with the business model of earning their money via microtransactions and DLC.
I think streaming and broad band infrastructure will come into it's adolescence and maybe even starting to mature, which will render what you play your games on, nearly moot.
The Social Media bubble will have crashed. We shall enter into a golden era.
Also there will be cake for all.
If mobile gaming suffer a crash, then chances are all of the gaming industry will be suffering the same crash as well.
