When Metal Gear Solid: Twin Snakes released on the Gamecube, it featured fully re-done voice-over work. A recent tweet from Hideo Kojima might indicate a similar treatment is in store for Metal Gear Solid: HD Collection.

The tweet reads:

"Re-recording for “MGS HD (MGS3)” in progress today, and the voice actors from MGS are here from the morning."

It'll be interesting to see if all the actors return, as some (those that voiced Mei Ling and Gray Fox) were changed when Twin Snakes' dialogue was redone.
