Because that contact was with Lucasfilm. Whenever there's a buyout those types of contacts need to get renegotiated. It's all legal mumbo jumbo that we never see behind closed doors. Hamill and Fisher both signed it away again they didn't care. Ford on the other hand obviously did. Or Is playing hardball who knows. As much as he hates SW I'm sure he or his rep are ignoring calls or wants more money than HT is wanting or willing to dish out.
As for Chan not happy with the sculpts, he seemed to not care with all the other OT and Indy sculpts that have been half assed over the years so I don't think he's just holding off because of that. Blade Runner isn't SW and he may have had to sign off on that when he agreed to the new film. Again more legal crap we have no clue over. As for Hasbro, do those even need likeness approval? Because they hardly ever look like the actors to begin with
Anyways the word from an industry insider is better than anything we won't be getting from HT or Ford on the matter hence why I said **** it and went custom. I got tired of waiting.
If HT does do another OT Han it'll be a too little too late at this point for me
EDIT: The renegotiating is the legal route nothing Disney can do about that. And yeah Im sure they aren't happy about it either but they weren't going to throw a (what was it 4 billion ?) Franchise out the window because one crappy old man wasn't going to play nice.
Star wars is bigger than Han Harrison Ford Solo
