I'm guessing we'll see re-skins of the other boxes at some point too. I hope they could fix / improve a couple of things about the OT with this update. Maybe a new software for both versions. Being able to p-lock multiple steps at once like on the A4. I just want some way to automate the midi arpeggiator transpose across a whole section without having to dial it in every step. I know I can use the arranger for this, but I don't want to use the arranger, I want it in my pattern god dammit.
That being said I like the UI change. While this isn't a new product, just a better version of an old product, I still like it. It's a bit like how the squarp pyramid just got it's MKII, but it's the same OS with a few cosmetic/ergonomic upgrades. This at least has a number of different button changes, there is no "EDIT" button, and now it has more dedicated buttons so that you can go into edit page for various features with function key. It also shows me that elektron still cares about the OT and isn't going to stop supporting it or stop manufacturing it in favor of it's newer overbridge-capable sister products (I couldn't care less about overbridge).
It's fine, if I were to buy a new one I'd grab the MK2 but MK1 is fine for me for now.
