It will be interesting if he addresses the GUI problems with Rack (which is ridiculously inefficient). The modules are similar due to licensing issues and popularity I suspect. Long before Rack 2 was available, a developer shared a VST version of Rack over on KVR, I'm going back 2/3 years here. I'm not sure if it's the same developer, but I suspect it is, as the bundled modules are very similar.
