Konami announced today that they will release Metal Gear Solid HD Collection for the Vita in "late June." Late June really isn't very far away, so it seems a little ridiculous to not have a release date yet, but I guess we can't be too picky in theory.
This portable version of the HD Collection that released earlier this year will include the infamous transfarring system that lets players share data between the Vita and the PS3. Sadly though, the Vita release will not include Peace Walker, just Metal Gear Solid, Metal Gear Solid 2, Metal Gear Solid 2: Sons of Liberty, and Metal Gear Solid: Snake Eater.
