Funny enough, if you go to the warhammer youtube channel and search for mordheim, there's a handful of videos that come up that have nothing to do with it as if they've stuck tags on the back end for videos for some reason. Then there's this video from March 2025 where the guy mentions painting a mordheim warband for some reason at around 3:15
He could have said Warhammer Quest, Underworlds, Warcry, Spearhead, but no he said Mordheim when they hadn't sold shit for it in over a decade by that point(and even that was after spending what, 8 years or so not supporting it?). Clearly they've got something sitting behind the scenes in development or waiting on a release window(which could still be years).
