All true and I know it is important to serve especially these clients with more up-to-date-products. But this is not what I'm talking about. Since UM2+ there was no new product for makers and there is still no product for beginners! So what I think a new product could look like is something between UMO and UM2+ or even below UMO. Or a cheaper, not that accurate but bigger printer. Or perhaps something to recycle brims, supports and fails: a shredder and a extruder for making your own filament... Or a modular upgrade for the UM2+ with e.g. a new mainboard (and firmware) and then options to add an filament sensor or (like you mentioned with Octoprint) a network connection or a camera or newer steppers or different hotends or or or...
But this is only my opinion and I do absolutely not know what is the marketing strategy of UM. I do not want to say they do something wrong, I wanna only say it "could be" a wrong decision.
Whatever the future brings, I'm totally happy with my UM2+ and I love the UM community and that's why I'll never regret buying a UM!
