I broke down and ordered one yesterday. Got the gold color. Have the OG Topside in SS, Gunmetal, and Black. Wanted something different for the dual.
I don't have much use for a dual battery squonk, considering many of my single battery squonks are 2x700 compatible, and I almost always vape under 35w. My Basiums have only been used a few times. If I like the Dual Topside though, I will still be in line for the YiHi version when it's released. Doesn't hurt to have one around if I get the whim to build low and need more power. The bottles being compatible with the OG and Dual is also a big plus in my book.
Still on the fence about the new Drone. If I wait long enough, they'll be sold out and I'll just stick with the Topside.

I would consider picking up a full black one if I come across it at a US dealer at some point. Not going too much out of my way looking for one right now though. Guessing the dual Topside will fit the need for me.
