Mish-Mashed character mechs (The Beetleworx) are still in. It's just that we've only seen two of the in-game variants: that Hades-headed one with the Lilo and Stitch guns and the car body and the Tea-Cup Spiders.
Plus we got characters being converted into Beetleworx like Captain Hook and some of his pirates.
And seeing as we got that robo-Donald, the Goofy seen in those sketches is probably in as well.
