On a PlayStation Blog post, the voluble driving force behind Metal Gear has been on about how great the Vita is looking. The man seems keen:
As for the multitouch pad on the back of the console, I do not want to force users to use it. The PS Vita has cutting-edge technology and it’s the best there is – especially with integration with the PS3 – and I am very pleased I can offer it to users.And also confirmed that the Metal Gear games will be upgraded to HD and then ported over to Sony Vita:
Peace Walker is the first step. It is a PSP game in HD that lets one go back and forth between one PSP and a PSP. The next step is to take PS2-quality games, such as Metal Gear Solid 2 and Metal Gear Solid 3, to HD and then to take them to Vita transferring.
