Awhile back, I remember the devs only committed to the PS3 through HW. Yoshi-P seemed keenly aware of how the PS3 would hold back the game, but he insisted on ARR being playable on it to meet the promise made by the 1.x dev team. Wouldn't surprise me to see PS3 support dropped after the next expansion.

Do yourself a solid and get a ps4. You'll never look back.
