Episode IX releases in theaters December 2019, so a blu-ray release in 2020, ad sometime after that will be an inevitable new boxed set that includes the entire saga (late 2020? early 2021? other?). I wonder if it will be 4K and will it contain the unaltered originals?
Disney will probably be clever and only include the unaltered originals in the 4K full saga box set. The only way to own the unaltered originals is to also buy Attack Of The Clones - that is the heavy price you must pay!
I cant even begin to imagine how bad some of the CG in the prequels will look in 4K a couple of years from now. I know Star Wars and ‘Special Editions’ don’t have a great track record, but if Disney came out and announced they were modernising the Prequels CGI up to present day standards for a Special Edition then I wouldn’t object!
