Konami released a rather polished trailer for the previously announced PS Vita version of Metal Gear Solid: HD Edition that walks through the Vita specific features.

None of the info seems new, and it's (mostly) in Japanese, but you should be able to follow along even if you don't understand the lingo and enjoy the slick trailer.

Metal Gear Solid: HD Edition goes on sale this June in Japan.
