When the show was released on blu-ray in Japan in 2015, they reanimated the entire show in high definition - much like the Cowboy Bebop remaster. Here's the OP extracted from the Blu-ray. This was also the version given to Netflix for streaming so I don't know why they wouldn't use the same master for the international release.Looks like I'm taking my Platinum Edition set with me to the grave. I also would love to see some reviews on the quality of the Blu before doing a preorder. It seems to be hit-and-miss with older animation.

EDIT: Forgot to mention the original 16mm telecine version of Episode 16 was lost so that was mastered from a video print that was upscaled and it doesn't look great but the rest of the show definitely looks stellar.
