How is it going?
I wouldn’t expect a release in quite a while if I’m being honest, the donors to this project never received a full grindhouse and presumably are not being consulted in spite of the money that they gave to fund this project.
If you’re looking for a 35mm preservation of AOTC you can view, 4K02 just came out on the TSWT forums, and is no longer in its grindhouse state and has been cleaned up.
