Any new mid drive systems of note?

I keep looking at getting a Bafang Ultra to modify a steel hardtail mountain bike frame I have. Luna doesn't seem to be stocking them right now. I see that there are usually some 6000-series STePs motors on ebay at about the same price. I have the part needed to mount one of those. Bafang has some new motors since the last time I looked, but the main difference is one for road bikes, which probably isn't the way I want to go.

A cursory search didn't reveal anything too interesting from Eurobike. Lots of new bikes, but I don't really want to spend that much.
