The luminary revealed the tid-bit in a roundtable featured in Famitsu magazine. He was joined by Platinum Games' CEO Tatsuya Minami and producer Atsushi Inaba.

The interview touched upon how the collaborative process between Platinum Games and Kojima Productions was being managed, something that was previously detailed in a documentary video following the game's reannouncement last year.

Interestingly, Kojima revealed that the partnership started getting serious at the PlayStation Vita announcement press conference last January.

Metal Gear Rising: Revengeance is due out on PlayStation 3 this year.
