Still in the works it seems but something definitely happened to have this particular work be delayed. One week after the initial teaser post, he said he sent it to VA already. Another week after that, he repeats that it's already been sent and wants to release it "hopefully soon".
Now, it seems like he's gonna release an Evelyn animation first before leaving a few days for surgery. So seems like it might out until March at the earliest. Hopefully it does get finished eventually, he seemed a bit unsure about it in the initial blob post about it.
