An image supposedly snapped at San Diego Comic-Con appears to have linked Hideo Kojima's Project OGRE project with Metal Gear Solid 5.
The unverified picture prominantly displays a logo for Metal Gear Solid 5 along with the phrase 'Open Ground Reconnaissance Endeavors (OGRE)' which could be a replacement for the 'Tactical Espionage Action' tagline the series has carried thus far.
A Konami spokesperson has declined to comment.
[UPDATE] Hideo Kojima has claimed the logo is 'completely fake'.
Over the weekend Gears of War creative director Cliff Bleszinski confirmed Kojima was showing off something "secret" behind closed doors at Comic-Con.
Just got pulled into a back room at Comic Con by @HIDEO_KOJIMA_EN and showed some crazy new secret stuff. Wow.— Cliff Bleszinski (@therealcliffyb) July 14, 2012
Among the images is also the logo for 'Diamond Dogs'. The logo was first seen on a piece of new artwork of Big Boss attached to a Konami recruitement drive for "The next MGS".
Kojima has alluded to a new entry in the stealth franchise on numerous occassions, saying he'll 'probably have to make Metal Gear Solid 5' eventually, confirming an 'authentic stealth MGS' will be released in the future, and discussing potential MGS5 ideas.
However, he hasn't yet officially confirmed the game is in production. Instead focusing his efforts on talking up the studio's new FOX Engine and Project Ogre.
Last year Kojima revealed that Project Ogre will be an open-world affair where players explore large environments freely.
More recently the Metal Gear creator said he intends to explore the 'concept of love, or raising a family' in the game.
Analysts at Japanese investment company Nomura Securities have said they expect the Metal Gear Solid 5 release to be during Konami's fiscal year 2014.
