Yes and no. They switched a generation ago to commodity architectures (likely owing, in large part, to the very slow developer uptake of Sony's exotic Cell processor). Playstation and Xbox have both been on x86 for the better part of a decade already. But this does not make them PCs any more than Nintendo going ARM makes the Switch an Android phone. The experience of owning, using, and developing for a console remains entirely different from that of a PC, even if the underlying hardware has more in common than it did in previous generations. It's not "giving up on the market" at all.
