You are probably thinking of Harmy’s projects which use a combination of sources to achieve a high quality version of the Original Trilogy. This is considered a reconstruction since he’s starting with the altered Blu-rays and working around them.

Mike Verta has scanned a number of original 35mm prints, including several that use a now-defunct color process that is closer to the negative in terms of generations (so it’s less of a copy of a copy…). He’s been using averaging techniques to take several images and only leave the parts that are similar, which should - in theory - remove generational grain and get an image closer to the original negative.

Yes it is exciting but this will only be released to the public as an official Lucasfilms product so it’s up to the executives there and at Disney and at Fox to work something out.

On the bright side, there are people working on their own 35mm projects the most famous right now being the Silver Screen Edition. It, unfortunately, suffers from weird scanning artifacts since it came from a homemade scanning machine. However we do have high quality scans of several prints of all the films in the series. All is good.
