Well I guess this way people can buy it on their preferred systems. Maybe some didn't bother with the PS3 or they're kind of done with it and now they're excited about the PS4 so they think to themselves "Sure why not? I liked the game!"

I won't get it on PS3 or 4 because I have it on the PS2 and it works just fine. But I don't have it on a handheld for traveling or when my boyfriend is watching TV or whatever, so this way it's worth the money to me to get to see the new sphere grid and job classes
