But the other side of all that "free money" you guys think these families and license holders would rake in, are lawyers, entertainment lawyers at that. My guess is that now that their family member is gone, they don't want ANYTHING to do with hollywood ever again, in any way, shape, or form. Some people just sour to that whole thing and will never be swayed by money. I'm not saying it can't/won't happen, I just think it's very unlikely at this point.
I'm sure they could physically, but I'm also sure doing so would require a whole new contract with Disney and if The Mouse doesn't see incredible profits(which they probably wouldn't since they're not making currently doing anything with Tron and wouldn't see the point of a new licensing contract for such a potentially small run of a very limited market item), they don't go in on it.
