Konamiannounced today that we'll be able to expect to see Solid Snake's debut on the PlayStation Vita on June 12, 2012. As you may know, the Vita version will be a bit different than the console version.
The major difference is that it will not include Metal Gear Solid: Peace Walker. It will, however, include both Metal Gear Solid 3: Snake Eater, and Metal Gear Solid 2: Sons of Liberty. The Vita version will also include a few Vita-specific additions such as touchscreen control.
Players will be able to use the touchscreen and rear touch panel to do things like zoom-in on scenes, peek around corners, cycle through weapons, and rapidly cut with the knife.
