Thanks for all the additional info Adrian, especially regarding 4K, good to hear considered responses and the rationale behind your decision makes perfect sense. It also sounds like the upcoming 25GB version might go a little way towards improving the image and upscaling potential on a big screen, so I’ll look out for that.
Regarding 4K in general, I think anyone in doubt should watch the newly released 4K edition of ALIEN, a contemporary of Star Wars, to see how remarkable ‘old’ movies can look.
