Could I buy a PlayStation. Yes. Will I, no. I lost interest in PlayStation back during the PS3. That console saw more Blu-rays and DVDs than games. Never bought a PS4.
And if/when this or any other formerly exclusive games come to PC, it has to compete with current release PC titles, but itself will be judged as an older title. It doesn’t matter to me if it’s new to the platform. I won’t be paying new game price for a port of an old title.
