I think getting a new boxed set or sets by the time of the home video release of IX is almost a foregone conclusion. I also imagine TFA and R1 will be out in UHD well before that, in the run-up to IX’s theatrical release. I-VI are the real question. I could see it going either way, with them being released in the fall to build hype for the new film, or in the spring to cash in on the completist urge that many of us will have with the full ST in 4K on our shelves. Celebration will tell, I guess (or it won’t; I’ve got a terrible track record for these predictions).
