I just came specifically to post the same thing. These have definitely grabbed my attention too! The price point seems ok compared to other companies who have released a smaller sized variant (I'm looking at you Sinn U50!)
I've only ever tried a Seestern homage to the 300T so I know that the dimensions aren't exact, but found that it wore quite nicely apart from being a bit too thick for my liking. This smaller 200T seems to address that issue.
EDIT: I've just looked on the Doxa website and the UK price is slightly higher unfortunately than the mental conversion from USD would be. So not quite as good value as I was originally thinking, but probably worth waiting on it coming to SC.
