Sweet! But...Tried to buy one yesterday. 48cm and 50cm both out of stock. MOQ is 30 sets, so they couldn't give me a timeline. They were also out of the handlebar I wanted for the build (380x90 but have 380x100 and 400x90). And now, because of your post, I'm even more depressed 
Maybe consider their other frames? I wouldn't order this frame unless you're absolutely sure the long reach is what you need (meaning: get a bike fit first). I built one up for a friend, and while it's a great frame, there is no way it can fit my body. There is no such thing as a geometry that fits all riders, so measure twice, or you'll have to buy twice

Regarding the MOQ: I don't think there's a MOQ for this frame (I bought a single frameset), but they probably mean they can't spin up a production run just for a single frame, so you're waiting for one of their OEM clients to order a new batch of frames first.
