The as-yet unannounced Final Fantasy XV Royal Edition has been rated by the ESRB, prompting speculation that Square Enix is looking to launch a repackaged version of its critically acclaimed 2016 JRPG.

While nothing is known about the Royal Edition at present (the ESRB description is identical to the original version of Final Fantasy XV), we'd hazard a guess that it'll cobble together the full game plus the extensive array of previously released DLC and other goodies.

Whatever it is, the rating confirms that the mystery title will launch on both PS4 and Xbox One. There's no mention of a PC version, though that's not surprising since the core game isn't out on home computers until Q1 2018.

Square Enix previously confirmed that it will continue to develop content for Final Fantasy XV throughout 2018. The game launched in November 2016 and has managed to flog a staggering seven million copies worldwide.
