He is right but he is also wrong.
He is right that the PC will outperform the PS4 or any other console but it matters little.
Many games are made for consoles because that is where they sell. If you compare game sales between a console and a PC, the PC business can be deemed almost as charity.
UbiSoft threatened the PC players several times with dropping support of the PC due to laughable bad sales.
CryTek who is basically the only company to challenge the top tier hardware these days is making a huge loss on every Crysis they put out there. They don't really care because their games are not their real product but only a prove of concept for their 3D engine. (So are the titles of id or Epic)
And even these guys had to make their engine run on consoles in the end to adapt to the market.
Boast about your PC specs all you want, I too own a very powerful PC and is my preferred platform these days, but for the average publisher this is not a platform they could focus on.
Mind you I'm not saying there is no business to be made on the PC. Valve is doing well and so is Blizzard or CD Project. But lets also be honest these are more or less the exception to the rule. Unless you cater towards a niche and/or keep your budget in check, therefore limiting how much you can use the hardware, it is rather hard to be profitable on the PC. (Blizzards games are always made with a not powerful PC in mind: Look at WoW, D3 or SC2, it has to run in South Korean internet cafès)
Valve is doing great due to Steam which is basically a console platform on the PC and still highly regarded by many (not me). Blizzard has WoW still paying most of their bills and CD Project is keeping their budgets low due to their location in a low cost country.
You can't expect everyone going these roads and being successful, it is not like they haven't tried: Uplay, Origin, SW:ToR and relocating Devs on a large scale to locations with tax advantages e.g. Montreal.
If your a publisher and you want to produce a game with high production value the only option is to release to the consoles. You can't pour 20+ Million into a game that may only sell 500k units. You need sales in the millions and to get that on the PC is very, very hard.
Deep Down and the new Killzone that where shown for the PS4 looked better than anything I currently run on my PC and my PC is supposed to be more powerful than the PS4 already. But it does not matter because there is no software for all that power I have.
Crysis may be more advanced technology wise (I don't know) but tbh it does not show. I'm wowed visually by Deep Down not so much Crysis. Maybe because I know Crysis is just a FPS and Deep Down could be anything in my omagaination atm.
I'm glad the new consoles are in sight. And I hope they are designed in a way that allows the companies involved to turn a profit in less time even if it means that they are not as powerful as they could be. I too think this cycle was too long but it was that long because Sony and Microsoft put out their hardware with a loss in the first place and that was due to the demand of players to get a stronger hardware.
Well that backfired in the long run didn't it?
Well lets see what the PS4 will costs I doubt that they will repeat their 599$ and 499$ mistake of the PS3. Therefore I say it may be 399$.
