Metal Gear Solid 5: The Phantom Pain could be scheduled to release in early 2015, judging by a supposed product registration page for this Friday's Metal Gear Solid 5: Ground Zeroes.

An image of the page (posted on Reddit) thanks fans for registering their copy of Ground Zeroes and tells them to "come back Early 2015 to claim your Downloadable Content".

The DLC is thought to allow players to use mercenaries rescued in Ground Zeroes as troops in The Phantom Pain.

Konami has yet to announce an official release date for The Phantom Pain, which is said to be "more than 200x bigger" than Ground Zeroes.

Metal Gear Solid 5: Ground Zeroes launches this Friday, March 21 on Xbox One, Xbox 360, PlayStation 3 and PlayStation 4. Head back to tomorrow morning for our review.
