I feel like they probably tried to do Mr Black, as evidenced by the data mining, then realised that since his head was a different size and shape to the rest of the Predators they weren't going to be able to make his mask fit everyone, like they've done with all the rest. So they scraped him and just gave us a mask that fits normal Preds instead. Sucks if that's the case, but I feel like it could be.
But yeah, it does finally seem like we're in a decent place map wise. It's certainly good for the people who picked it up on Steam recently. They're getting an amount of maps the rest of us had to wait a year for!
