If there is a new release coming up in the near future, be it OOT or SE, I expect it to be around this time next year, when we’ll have our first holiday season of the Disney era without a new film. That seems to be the perfect time to drop a rerelease without it distracting from anything else.
That’s also when Solo will be out on Blu Ray and DVD.
I’m pretty sure TFA and R1 were both released on home video in April, and I saw somewhere the other day that the TLJ blu-ray has been confirmed for April 18 in the UK. Assuming the same four-month lag for Solo, that puts the disc in late September. Still plenty of time after that to drum up excitement for a Christmas OT release.
