Square Enix has announced a new expansion for Final Fantasy XV: A Realm Reborn and this is completely different from the patch 2.4 that will add a ton of new content to the game.
Heavensward contains new areas, new primals to fight, new jobs and race and also increases the level to 60. This would presumably be patch 3.0.
Final Fantasy XV users will be kept busy by patch 2.4 and suddenly it looks like there’s going to be a complete overhaul of the game just when people were starting to get bored. I myself canceled the subscription but looks like I may have to subscribe again.
Here’s a teaser trailer for Heavensward and it looks pretty stunning. It will be released in Spring 2015.
