The PS3 and Xbox 360 remakes of Metal Gear Solid: Peace Walker support four-player co-op on Xbox Live and PlayStation Network.
Kojima also noted that, "During loading, characters' dialogues pop up at random."
But whether Peace Walker HD will have split-screen co-op as well is currently unknown.
The transition from PSP onto PS3 and Xbox 360 has also brought Peace Walker 60 frames-per-second.
The PS3 and 360 remakes of Peace Walker are part of the Metal Gear Solid HD Collection.
The standard Metal Gear Solid HD Collection includes Metal Gear Solid 2, MGS3, Peace Walker and Metal Gear 1 and MG2.
The Ultimate HD Collection adds Metal Gear Solid 1 and Metal Gear Solid 4 to the mix. That's available on PS3 at Zavvi for Ł70.
