Not really, your logic isn't really understanding the whole point of a business model. Sony own PlayStation and Naughty Dog is owned by Sony. Why would they allow one of their own companies to utilise their talents and make a game for their rivals Microsoft? It's all about sales these days, TLOU being a PlayStation exclusive more or less gurantees more PlayStations being sold. Sony are near enough swimming in money as it is, seeing as they sell things like headphones and TVs.
i think i got your point but i still don't agree with the way it's done i already own a ps3 but if i didn't i would not have bought myself a ps just so i can play a TLOU that would be a pretty damn expensive game than so i wonder if any body would have
