7. Shulk
Shulk appears in the very popular Xenoblade Chronicles and for me would again be a 'step in the right direction' for the franchise if Namco want to ride the very high popularity of his game series. Shulk has a high variety of moves via his Monado Art skills which include Purge, Cyclone, Eater and more defensive moves such as Shield and Speed. He can also use his ancient sword as a weapon in itself so would appeal to many gamers who want to go for a classic 'warrior' approach rather then the snazzy magic or abilities offered by other characters.
