Save data of Ground Zeroes on PS3 can be transferred to The Phantom Pain on PS4
Good news for those who are planning to get the PlayStation 3 version of Metal Gear Solid V: Ground Zeroes and continue the story with the PlayStation 4 version of The Phantom Pain: the save data can be transferred between the two systems.
This was confirmed on the official Japanese site for Metal Gear Solid V. It makes sense since there will probably be a lot more PlayStation 4 owners when The Phantom Pain comes out than there are right now. Kojima himself said that The Phantom Pain will release ‘when there are many of PS4 owners’.
