A Korean classification rating for something called Metal Gear Solid: The Legacy Collection may point towards a MGS compendium on PS3. The rating notes the PS3 platform and Konami as the registrant. Meanwhile, a tweet from series creator Hideo Kojima points to some sort of collection including the first four numbered MGS games, as well as Metal Gear Solid: Peace Walker.

That's based on an image Kojima tweeted earlier today (see below the break), featuring the different guises of Snake across the five games, emblazoned across the words 'METAL GEAR SOLID.' Then again, that Kojima's a bit of a cheekster, so maybe this is just a front for the almost inevitable Joakim Mogren spin-off.
