Well Python you’re ahead of me with the information, i haven’t seen any ‘postponements’, it’s just been crickets far as i can tell.
Odd that Waldorf still has the STVC on their hardware product page, and retailers in the US still let you pre-order it, but Waldorf has never put up a manual or any mention of when, that i’ve ever seen. I think there was some non-official question about changes and improvements (like in an interview with Rolf), in particular to add the storing/loading of freezes – which would be an excellent feature were it ever to occur.
Waldorf has their own schedule with things, for instance the Quantum took it’s time coming. This can be a good thing, if it means that what they release is better for the wait.
