So assuming Final Fantasy XV does release in 2016, will Pokemon eat its lunch, or will the separate ecosystem keep it safe?
But how much it will eat into it is a different matter. It could be very minor, to the point of irrelevancy, or it could be noticeable. Used market being strong and FFXV being single-player means there's no real rush if you are otherwise engaged in a different product. And the I'd wager that most everyone who owns a PS4 probably owns a 3DS if they are j/RPG fans.
