Investing in Elektron devices can be done for three objectives:
a) for having fun making music on them, you invest in a joyful life. Your mk1s still make music, you can still have fun with them, so no disinvestment from the mk2 announcement;
b) for making money through stage performances or releasing songs using the devices, you invest in your career. Your mk1s still make music, you can still have fun with them, so no disinvestment from the mk2 announcement;
c) selling your gear at a higher price than what you bought it for. Either become an Elektron retailer or regional distributor, or buy cheap second hand. Or consider not selling but renting them to customers.
All fine!
But please stop whining about how Elektron misled you into losing money, because they have not. That is complete and utter nonsense.
