Watch 10 minutes of Metal Gear Solid Ground Zeroes’ Demo shown during the Metal Gear Solid 25th anniversary panel at PAX Prime.

“We’re not going to say that it’s Metal Gear Solid 5,” Kojima said after the demo, “but it is a prologue.” Kojima also confirmed that the demo was running on PC hardware that was similarly equipped to PS3, and that the final game should closely resemble the demo video.
Kojima also confirmed that he is personally creating Ground Zeroes.
