I can't see another hulk for this license. Not anytime soon anyway. With the amount of figures coming it seems unlikely. Already two versions. With three figures essentially. From a business stand point it wouldn't make a ton of sense. I could see an accessory pack like the stark stuff. Maybe another head and shorts with some other stuff. Or do a banner with added head. I just don't see them making a third hulk from one film, when they have multiple 350+ dollar figures, and 10 total (at least) figures from one film. With a JL move coming, a JP movie, a new Terminator and alien movie coming, a new xmen, F4, and those are just the group flicks. Not counting rebooted spiderman, and all the individual movies (black Adam, dr strange, ant man, another thor, Aquaman, ect).
Any things possible. Just seems very unlikely.
