It is a bit strange though isn't it... having not long released the 4K steelbook set and disney now being disney and making the 5th film

They've also missed the 40th anniversary by a year, which may have been the original intention for a final milking.
it does seem odd, although perhaps no odder than releasing a
Matrix box set weeks after releasing part 4 on its own...
i would pay good money for all films in premium or even premium-lite packaging, perhaps a wooden ark of the covennant box (like an edition released years ago when there were only 3 films),
with the bonus features which never seem to 'feature' on releases anymore.
but with a 5th film coming, 4k only (i have and like 4k, but i don't like releases being restricted from people who do not), and no details about the other films, why would i buy this? particularly when i see your company not being able to shift the 4k box set of all four films, as lots of people didn't like the (not original poster) artwork?
