Haven't seen it brought up here yet, got an email from AllTheAnime a couple hours ago wrt Violet Evergarden, blu-ray release is delayed because of the video quality, their looking at the masters to see if the can re-author and replace them prior to release, no estimate of new release date.
Personally, while I was still holding just out a little bit of hope that it might ship before xmas, I'd much rather get the best release possible when it comes to the video quality of all things, so I'm totally okay with the delay and really hope they can do something about it.
A couple of things to note from the email;
1) From the sound of it, they are uncertain of were the problem is, if it's a problem with the encoding not present on the masters then looks like they'll try to re-author them, but if it's an issue with the masters themselves we might be in for a disappointing release in spite of the delay.
2) They did refer to "looking forward to receiving shipping notifications imminently", so presumably they were kind of on track to at least ship the early bird pre-orders from alltheanime.com soon, so the delay may only affect that, and not the given retail release date of 11th January, but I'd imagine it'll only make that date now if they
can't do anything about the video quality...
EDIT: silly me, was already a conversation on this in the one place I should have looked first, the
Defective or Disappointing UK Anime Discs thread, my bad...
