As a PC gamer I'm worried, maybe more than console gamers. Google and Apple should worry too, not just Sony. Sony will be hit, but it's not MS' main target: Spencer and Nadella finally show they understood (they understood it immediately, but they didn't show it until they were ready) what Ballmer and Mattrick didn't, that the true important target is the mobile market (gaming is important, and potentially very lucrative, but mobile, including its gaming part, brings money and a LOT of power) and that MS' most dangerous competitor isn't Sony, Google and Apple are.
