The only thing that would make me hesitate to continue with Cubase Pro is subscription.
I came from SONAR and the beginning of the end came with that subscription model. And it was a “kind” model (you could keep the software after closing your subscription). I would never like to see this with Steinberg. At the beginning SONAR gave us monthly interesting updates, then asked to pay more. And then the updates became less and less interesting (a new button, a bug correction…) then they stopped all of this and kept my money…
Subscription is something that is good for the vendor, not for 90 % of the buyers… It’s also an open door to immoral rules. For example, Magix has a kind of subscription model for graphics or video software. You pay and you can expect one year of updates. But if your computer crashes after this year, you can only reinstall the original software (without the updates…).
On other niche markets like 3D animation, it was a way to oblige the consumers to pay more than you can believe. For example 3DS max = 2000 € / year…
