I'm not surprised about the lack of Predator mention considering the reaction to The Predator and that it was only just last year. This year is pretty much the best time to get people hyped for Alien content so it naturally makes sense to push since Covenant is a few years behind us now and we're on 40.
I don't doubt the Disney era will produce a Predator film, it just makes sense it isn't a high priority right now. Makes sense its in the sizzle reel, make sense it's not a high priority.
