And Harrison Ford on it:

Surprisingly, he's...interested?

Well not only did he have to deal with Han not dying, he's had many years to mellow about it and perhaps to see more opportunity in the role 30+ years later than he saw 3 years after ESB. Different kind of situation, but it reminds me of Tom Baker declining to take part in The Five Doctors and he later regretted it. Ford has the benefit of not regretting!
