i'm not going to be keeping all the files. It's pointless worrying about future formats. 720p is going to be the highest quality these edits will ever be in. Its going to be a very long way down the road before anyone buys into anything better than Blu-ray / 1080p. I saw a demo of the 4k Tv sets and to be honest, unless your Tv is going to be larger than 60inches, it just isn't worth the money. There isn't that much difference between the lossless original and the rendered BD-25 blu-ray encode. And, as 005 said, the blu-ray transfers aren't all that great anyway and the prequels are stuck at max 1080p, so what ould be the point?

I will not be gong back to this movie once it is finished and out there. I want to move on and not have to worry about some new format coming out that might improve the quality somewhat. By the time i have finished all these movies then that's it. Nothing more from me. No more edits, ever. I need to get my life back ;)
