I received the word from the organizers that this event is still on this year (unfortunately, my plans have changed due to COVID, and I won't be able to attend).
Nevertheless - this is what I received from the organizers...
"You can give your friends in Germany our contact (office@jcc.ch), we'd love to have them here. Or they can contact the Swiss De Tomaso club (www.detomaso.ch), the event is on their programme for this year- they're apparently quite enthusiastic about the meet. Looking forward to having you here another year!"
