It appears Arturo Manzano, MD of AXISS Europe (J-OEM HiFi distributor) is heading a company called Analog2Fidelity that will make 'Koetsu' cartridges again using the people originally involved. They've been active since October offering Koetsu rebuilds but it seems they now intend to make continuation Rosewood Signature, Urushu Wajima and Urishi Vermillion.

There may have been a small discreet company behind this thats just got new backing and employment but my suspicion is that Koestu were actually made OEM by other cart manufacturer(s) in Japan over the past 20 years or so. I recall that Scantech (Lyra) were involved with this previously. Whoever it is, possibly against the Koetsu families statements (?), will just continue to make them since they have all or some of the know-how, processes and parts access. Its not clear if they will be badged as Koestu however. The press release is suitably vague.
