One thing is nice, though, is that OP-1 is neither discontinued nor replaced by a mk2 that would make further updates inaccessible.
About the crazy price, this was the trick a former boss of mine was using when he didn’t really want to sell this particular product at this particular time, while letting the door open for happy accidents (as in customer in a hurry / absolutely needing the product).
I would assume this price will go slower once TE is ready. Might be next Black Friday, though.
Got my second hand OP-1 480€ in 2014 when the price new was 700€.
While I love the OP-1, I wouldn’t pay more than 700€ for it. Above is way too much, IMO.
