Useless for fantasy, obviously, unless someone run a Steampunk theme. Seen not through a fantasy lense, I find them weird and quite fantastic. Sure, too long-legged and maybe a clutter of details, but it is nevertheless an imaginative rebirth of Squats. At long last! I'll have to get some for my Squat army, maybe as an engineer's guild private army on the side of the converted Mantic Forgefathers and those 6th ed Dwarf bodies I
converted into original Squats. Hobby omnivores get to enjoy lots of different styles.
They're certainly in their own sci-fi/steampunk/magitech niche and have nothing to do with classic fantasy as in Warhammer and Tolkien, but they're not horrendous for all that.
And most importantly, despite all the recent upheavals it is a sign of health that Games Workshop still has their Dwarf preference going strong. Magazine named White Dwarf, bar at Warhammer World named for Bugman the brewer, Dwarfs first army out for 7th edition before that edition even had hit. And Dwarfs last out of the official Warhammer Fantasy Battles run as the very last army book released before the End Times. Now in the strange setting of Age of Sigmar, they've already released two Dwarf armies, regardless of how useless they might be for WHFB.
I'm glad miniature producers like Avatars of War and various other minor companies will continue to shoulder the fantasy miniature (and more importantly the fantasy Dwarf!) niche now that Games Workshop is seemingly retreating from it. Oldhammer style model lines have an especially important role here, since the old metal Dwarfs up to and including 6th edition sported a ton of character, and some fun joker bits as well.
