If you aren't already aware, Steve Ozer and Kyle Wlodyga (formerly of Super 7) from Mattel were on Gotham City Tonight a couple of months back. They were showing off the kids line, but that is actually a different team and these are guys are working on the collector's line. They didn't say a single thing about the collector's line (nothing until 1/1/27, according to them), but at least they are willing to be public facing. And you've got collectors working on the line who don't exhibit the narcissistic tendencies of Nite-Lik, so that is a positive sign.
EDIT: Bill Beneke is still at Mattel as well, looks like he worked on the kids line. Steve posted on Instagram a few days ago.
