Well, I don't think many of us would want it now with a new and improved home video release probably happening later this year. As much as I like the film and if I didn't already own the 2013 Blu-ray, I wouldn't buy it now.
It doesn't look like Warner is releasing this on 4K/UHD disc. A Blu-ray release is coming and will be on HBO Max later this year.

Well, what you linked isn't confirmed by WB which is what you stated! That doesn't mean it's not going to happen, but until we see an official WB announcement it's still rumors. Here's hoping it's true!
I had a feeling my stated preference for 4K disc would elicit a response from you because I know the best part of film isn't in 2K. However, I'm a fan of applied HDR even though you aren't so, particularly if applied to older films. I understand that could change the look of the movie from...
Yup, looks like in 2022, we're getting a new BD release, but perhaps 4K/UHD release. I hope it's the latter.
Edit: On second thought, a 4K disc is out of the question due to the film elements and how this movie was filmed. Perhaps, a second BD release could be coming our way.
