For anyone wondering exactly what happened to Sony Creative Software (SCS) when it sold Vegas et al to Magix, it's safe to say that SCS is no more, and Catalyst will die on the vine with it.
What you'll read in the link below are comments from staff who used to work there. They urge Magix to retain the incredible SCS talent (which is a good idea) and to continue to find a way to build on the concepts of Sonic Foundry/SCS.
It's a sad day.
