True, but if you're talking about competitive gaming to the point where people are picky about who they play with then on a PC you're going to need a 120hz+ monitor, and for a decent one of those we're already at about one third to one half of the price of a new console. Not to mention they all use gaming headsets, mice, mousepads and keyboards, all of which can run from 50 to 250 dollars a pop (AUD). And even though you can be thrifty with PC building, and a well built PC will easily outlast the lifecycle of a console, the point is that if you're a pro gamer, competitive gamer, or even someone trying to break into that scene, then you're going to stay relatively up to date with your PC. Which means a couple hundred dollars here and there every few years most likely.

I think my original point is this though, if you think yourself a competitive or pro console gamer, then you have to buy the new PS4 pro because that's the gig you signed up for. Just like how a full time streamer will have to keep his setup updated with the rest of his fellow streamers. If you take your gaming that seriously then companies will probably try to force upgrades on you because they think you'll buy it. If you don't like that model then you simply complain with your wallet and don't buy the thing. But I personally don't think it's going to hurt console gaming in any big way because in my opinion the numbers of people who will upgrade will be limited, and the people who wait this long to jump in to the next gen of consoles usually do so to get a reduced price on the console. Not to pay what they could have paid 3 years ago.
