UPDATED Aug. 15 at 8:06 a.m. ET: The delay is official. Square Enix confirmed in an overnight email that Final Fantasy XV will come to PlayStation 4 and Xbox One on Nov. 29, two months after its originally scheduled Sept. 30 launch.

A statement from director Hajime Tabata notes that the delay is necessary to ensure that the game runs well when it does launch. Rarely do short-term delays like this mean bad things for the game in question; they almost always serve to make it better.

Read Tabata's statement below:

From the moment we joined this project, our vision was to create a level of freedom and realism previously unseen in the series. Regrettably, we need a little bit more time to deliver on this vision and are confident that this new release date will help us achieve this. As the director and lead of this project, I wish to personally apologize for the additional wait. As a team, we want Final Fantasy XV to achieve a level of perfection that our fans deserve. We kindly ask for your understanding.

Final Fantasy XV is 10 years in the making, so what's another two months?

The next numbered entry in the long-running RPG series from publisher Square Enix reportedly won't be making its Sept. 30 release. The rumored new release date is Nov. 29.

Word of the delay came first from Gamnesia, which cited "a source within GameStop management." The source noted that some stores have already received date-adjusted promotional materials, with orders to hold them until after Sunday, Aug. 14.

The report was later corroborated by two additional sources, one from GameStop and another "non-retail" source, speaking to Kotaku. Gamnesia also published an image showing GameStop employees how to update existing promotional materials with the new date.

Continue to regard this as a rumor for now, while keeping a few important factors in mind.

For starters, release delays are common in the later weeks of the summer. Publishers juggle scheduling around to accommodate last-minute finishing touches on games that need them. Final Fantasy XV is a massive game, and its director noted on the record at E3 2016 that optimization has been "very difficult."

It's also worth noting that release delay leaks frequently come from retailer sources. Stores like GameStop often find out about date changes ahead of official delay announcements so they can be ready to replace misleading promo materials.

Square Enix has yet to confirm any delay Final Fantasy XV, but Mashable reached out for confirmation and we will update this post as soon as more details emerge.
