This time, new details have surfaced to further whet our appetite.

According to a forum member at the NeoGAF forums who claims to have acquired the latest issue of the UK's Edge Magazine, plenty of Metal Gear Solid 4: Guns of the Patriots features you probably haven't heard of were unleashed. Here are the highlights:

• Ending will blow you away
• Snake needs injections to stay alive
• Snake will have two new energy bars that makes Snakes advanced age impossible to ignore
  
• Stress changes depending on fight conditions and can improve accuracy or Snake's ability to sustain damage, but can cause him to become exposed to his illness; can be reduced by smoking a cig
• Psyche is Snake's general state of mind, balance with stress affects progress.
• There's something special about the camera that Kojima Productions is keeping in tight wraps
• Secrets and other content won't be discovered until months or even years of play

Other promising factoids were mentioned, like Konami's Metal Gear Solid 4: Guns of the Patriots offering players highly detailed and fashionable consumer gadgets to toy around with. Stealth is still intact, but utilizing air ducts and sneaking past cameras have become fast paced. The game's production values was also said to transcend modern video games, defined as "more suited to Return of the King than Halo 3."
