cough The 2012 version was more exposed, fragile, therefore sometimes it broke apart at the saddle. This one looks sturdy. The disk part and Technic beam was "sticking out" in the original version too, even more than here where the fabric wings at least cover some of it. Plus it meant to represent the original play feature of the Ultra Dragon, so I don't see a problem here. At least it is well recognizable. I don't know if people were complaining about the Technic beam in 2012 but now they surely don't when they look back at that model so what changed? Nothing.
To me, the body looks well build and stabile. But I don't think the legs are thaz close, this is only one angle! Wait until we see it from other different angles of the set before you would judge it with an overall complex review.
I see this set is getting the "judging way too soon" flow which happened many times before, with many various set and which sets turned out to be better than they thought, so I would abstain from too early critiques until we see the actual set.
Side note: I heard it might be possible that it is actually a combanition of the Hunted season dragons.
