There's no really need for widescreen version, just stretch the picture to 16:9 mode by messing with your telly's settings and that's it. Keep in mind that this method will reduce cleaning effectiveness to ~80% of original because cleaning area is a bit larger than normally, so you might have to run clip three times instead of two for getting satisfying results.
Maybe one of the editing pros around here can grab this and make a proper anamorphic transfer.
The source seems to be a German cleaning tape. that means it's a PAL release. I think there should be a conversion to NTSC. Or perhaps someone can rip the NTSC version.
A new release of Star Wars is like a box of chocolates, you never know what you're gonna get.
Brilliant!
