This is where the PC master race argument always falls over IMO. The new consoles are both PC's, custom built to do the job of playing games. While the PC's we play on have to be able to cope with any kind of task we throw at them, retain compatibility across all the different part makers and of course run Windows/Linux/OSX etc. Meanwhile the Xb1 and PS4 have stable hardware builds which developers will leverage more and more from over the coming years, just as happened with all the previous consoles and even the Amiga/C64 early 80's computers.
I interpret the "Master Race" argument differently:
Until the mid/end 90ies, we had a plethora of appliances for gaming (consoles, home computers), watching TV (SAT receiver, VCR, separate TV), music (LP, CD, tuner, AMP, cassette deck..) and each of them had to be mastered individually.
Starting Mid-90ies, the PC started to consolidate everything and provide a reasonable abstraction between common hardware that is needed to run the system in general, and specialized hardware for the task (e.g. media PC with DVB-S card for TV and SPDIF for connection to amp). We also started to have an abstraction between operating system and applications, so you could configure your stack (HW, OS, Applications) as you wanted.
Today, there are those who have mastered common PC technology and have a relatively stable, easy-to-manage and low-TCO home IT environment consisting of standardized parts and solutions, and those who failed to master it and still stick to a plethora of appliances (including consoles, tablets, proprietory set-top boxes, home-routers, smart tvs and DRM-polluted offerings such as Netflix or Amazon TV).
