Nobody knows who this guy is, what his deal is, or if he's going to even be in the film, so how could anyone make the leap that he's going to be an important bounty hunter? Well, they don't, but considering the detailed concept art the film's artists have conjured up for the guy, you can at least assume that the character holds some importance. The facial augmentations, ragged look and general look of "I don't give a damn" that the concept art gives off, meanwhile, are all extremely evocative of a bounty hunter. Unless you still believe J.J. Abrams will be incorporating elements of the Extended Universe books (he won't be), then Jango and Boba Fett will both be very dead come the events of The Force Awakens. Unless Boba continued the cycle of commissioning a clone of himself like his father, then The Force Awakens is going to be needing some new blood. The assumption could be completely wrong, but this guy certainly looks like he could be one to shoot first and ask questions later.
