PC has never been a singular platform like, say, PlayStation or Xbox. Instead, it's a series of disparate landmasses sharing the same turbulent sea. PC gaming looks to become more fragmented than it's been in the past few years---for better and worse. More options means more chances for new ideas to flourish and, perhaps, for a new middle class of developers to emerge.
As ever, PC remains at the forefront of gaming. Whether it's the platform's advantage in hardware, its role as a breeding ground for interesting indies, or attempts to solve the mind-boggling logistical problem of offering nearly Every Game Ever, PC leads so many dances that you'd need to be a human centipede to keep up.
