3D BluRays are still being released in any case.
For current movies showing theatrically in 3D. I can’t imagine LFL doing the work to finalize 3d blus of the SEs for home video alone, and the theatricals are confirmed quashed.
Smaller labels like Twilight Time have been releasing titles from the 1950’s for a while now. Others are mining the '80’s. I fear by the time I can get my hands on a 3D set, they’re all going to be out of print.
