So the new sets only seem to be available in Hong Kong thus far. I picked up a couple from Toys'R'Us, and have reviewed the first of them on my YouTube channel. I believe this is the first review of this set on YouTube. Not up to the professional standards of Jang and the like, but I hope it's useful for people.

I'll build and upload videos of 75180 Rathtar Escape, 75182 Republic Fighter Tank and 75186 The Arrowhead over the next few days. Not picked up (and have no particular plans to pick up) any of the other sets.
