Honestly, I’d take a new transfer of the SE. I wouldn’t be thrilled about it if it wasn’t released alongside the OUT, but I’ll support anything that results in that awful Lowry master being retired.
I think a home release of that in the absence of an OUT is unlikely. There’s not enough AV nerd Star Wars fans out there to make it worthwhile. Your average fan isn’t going to buy it if they already own the box set.
They’ve been pretty successful so far in the “getting fans to quintuple-dip on a marginally-better-or-actually-somewhat-worse-but-newer! release” strategy. I think it’s reasonable to assume they’d keep it up, at least until they make a release that actually doesn’t sell.
IMO, the best-case scenario for the Reliance work is more and better raw materials to despecialize. No scenario involves something I’d want to watch, that’s just fantasy.
