It appears Kojima has made that decision a relatively easy one, as a tease on Twitter indicates that the PlayStation versions of Ground Zeroes, will be getting exclusive content. If you look closely at the poster in the image above, you'll see the following text:
Metal Gear Solid V Ground Zeroes
Prologue to Metal Gear Solid V The Phantom Pain
Takes place in 1975 after Peacewalker and nine years before the phantom pain
Multiple missions and central story and side-ops missions
Exclusive content for PlayStation platform
