Steinberg does what they want. We pay, or we don’t, depending on the value we hope to get from update.
I’d pay 50eur for a good update, with important improvements and new features. But will not pay anything for just new colors in mixer or something trivial like that.
If they put in a new sampler, like a good built-in version of Halion, say Halion SE, with 7.5, I’ll surely go for it even for 100eur.
Depends on the goodies that will come with new update. There is plenty going on with other DAWs, mostly in area of workflow, lots of very good solutions. If Steinberg implements at least some improvements that other DAWS already have, it will be a good value for a paid update.
