I’ve been following Elektron long enough to feel comfortable saying that yes, there has been a small drop in quality with their products. Would stress “small” there though.
I speak from experience but casting my mind back to the A4 and AR’s release (I think I came to the party a little shortly before the A4 announcement, not sure) I do remember there being various posts about issues with the OT and Analog series. Remember “paint-gate” anyone?!
What I would say though is that Elektron as a company are incredibly helpful in solutionising issues found.
Anyway, what’s gonna be next? Would be nice if they kept it simple and put their excellent delay & reverb into an Analog Heat sized box with enough ins/outs for the OT to take advantage!
In terms of synthy stuff - I dont see anything pure analogue in their future (other than maybe an update to the AK. Someone mentioned a DT+DN combo which would be insanely cool. So too would be something like what DSI did with their prophet X combining digital and analogue worlds.
