Even if ST3 ever happens, I doubt I'll upgrade.
I've meanwhile collected a nice set of tools from other companies and the upgrade procedure of the TRackS CS (which I still consider good stuff) taught me a lesson! You download several hundred MBs, install and authorize it and nothing really is installed/working until you push some button in an custom shop application which crashes without internet connection!!!
I just was
not possible at all to get it working without an internet connection. IK support kept giving me useless posts on what to try. I wasted a week until I dismantled the DAW and dragged it to a room with internet just to push that bloody button ...
For all serious users who keep their DAWs of the internet this is an harassment. This experience and all the iToys releases really make me wonder whether their software is still intended for high quality applications or if it's just trash ...
