Zeta & Dimension pro are working in samplitude; I just had to give it the appropriate VST directories.  Just lettin' ya know.

Yes, those and Rapture, and the L-Phase plugins, and probably a few more, are unlocked VST3, AAX for Pro Tools, AU for Logic, etc.
 

I noticed that last night as well, at least for some plugins. But even though they work now I feel hesitant to use them on new projects - the same feeling I get when working with Sonar at this point.
 
At least the 3rd party plugins (AAS, Overloud, etc) are still in production.
 
I do not want to take my DAW off the network, I've been looking forward to real-time remote collaboration for too long to do that... a couple of the applications I'm looking at seem to be going that direction (Steinberg's been at it for a while, more than likely others as well)
