I think so too. It’s a 50% discount on a subscription, as an offer to perpetual license holders, so that discount will probably be temporary, offering a band-aid for current ZBrush owners, so they might not leave.
This is the second time a big CG corporation managed to get me to leave. I used to be an avid 3ds Max user until Autodesk went the subscription way in 2012. That was the moment I decided to completely switch to Blender, after already having explored it.
It’s not that I don’t want to pay for my software, I just don’t want to rent it forever and never own it. At the moment I’m a Patreon supporter of the MagicaCSG developer. Supporting small-scale indie development feels much better than paying pricy subscriptions to big commercial corporations.
