One thing giving me hope is that we’ve gotten a reissue of the 2011 blu-rays every two years, which means we’d be due for another one this year, which just happens to be the 40th anniversary.
So, unless they want to give us the same discs yet again, they’ll come up with something entirely new to sell us.
I was so, so sure we’d be getting something new in the lead-up to TFA in 2015, and then all they did was steelbooks (although the movies were finally released individually at least). Even if they don’t bother with a UHD release just yet, I can’t fathom how they would repackage the blu-rays yet again without something, anything, that isn’t just a fancy container.
