People criticizing the consoles for not improving PC gaming, what a joke. Even Anand, on his review of the Xbox One said that it would take 18-24 months to see some of what the consoles can do. Personally, I'd say 3 years.
The PC Failure Race/Intel/NV fans don't want to see or understand that 8 x86 cores and GCN(Open CL, HSA, HW Audio) was the best thing to ever happen for consoles to push PC gaming forward. Who cares if 4 faster cores are better? 8+ OOE Multi-core/thread programming is the future, consoles being multi core pushes that move faster. How many games actually use 4 cores? 6? 8? 16?
Even Sony stated that the reason the PS4 has what it has, PC Tech, was to speed up development time, to make it easier to start.
But just because its general PC hardware, it doesn't mean that the world is full of developers who know anything(low level) about it. That takes years and many people.
And if its designed for 30 FPS, I expect low input lag.
