Also interesting is that they also added the capability to mount to an iOptron or the Sykwatcher AVX tripod.
Yup, but you'll have to buy the adapters for those as well. That's why the instructions say to remove the silver head plate from the extension first. The adapter (sold separately) goes in its place. But it is very nice for them to offer everything as a system.
I wish they would sell a "roll your own" kit instead. You'd get the top plate, bottom plate, then specify which tripod adapter (zwo, sw or ioptron) and whether you want the tube, pillars, or both. A nice a la carte menu. You can buy what you need now, then add more pieces as you go.
