All of this 4k talk has made me completely forget about the 3D versions of I-VI.
TPM got a theatrical 3D re-release in early 2012 but never made it to 3D blu-ray. The stereo conversions of AotC and RotS were finished shortly thereafter but have only been seen at fan conventions.
Then there’s the OT, which they were doing tests on as early as 2007 but was never finished.
TLJ and Solo didn’t even get a 3D blu release Stateside, probably because Disney put out the UHD versions day-and-date with the regular blu’s and wanted to push that as the premium SKU. I’m guessing there’s simply more of a market for home 3D in the UK than there is here.
