Who are the characters in Final Fantasy XII: Revenant Wings?

The sequel to Final Fantasy XII is coming out in just a few months and we know for sure that Vaan and Penelo are the stars. Llyud a new character, a noble warrior with wings who is part of the Aegyl race and Ba’Gamnan who was hunting Balthier in Final Fantasy XII is also confirmed to play a role in Revenant Wings. According to the silhouettes there are still a handful of characters that we don’t know about. The first two look like Balthier and Fran. They have been confirmed to be in the game so that’s probably correct, but what about the six. Anyone have guesses? I doubt that the silhouette all the way to the right is Zalbag, but that would be another cool tie in to Final Fantasy Tactics wouldn’t it?
