How is that different from every other console release in the history of consoles... they are always behind. But they are different markets.
It's like saying: "The iPhone X is years behind the latest PC chips"

Your iPhone "argument" makes no sense, it's a red herring.
PCs serve the "PC market" (A subset of that is the High end gaming market that enjoy keyboards and mice).
Show me a Street Fighter tournament being played on PC?
Or a Starcraft game being played on Consoles?
...
The reason you can't find those things, is they are different markets.
With the new PS4 x86 + GPU architecture, portability becomes trivial.
PS4, essentially, is a PC stuck in one configuration.
Fighter games, in general, are on consoles. You simply just don't play them on PCs. Similarly, RTS games are PC only; the only RTS on console I know of is Halo Wars, which sucked.
Just these two cover ENORMOUS markets, with Starcraft tournaments having millions of dollars in prizes, etc, yet are based on entirely different markets. PC vs Consoles more accurately share _subsets_ of the high end gaming market, which overlaps in some places (like Call of Duty), and differ in many others.
