Well, I guess Pluggo became Max4Live and the Kore2 wrapper thing went south as well. There are certain FL fx generators that seem to fall into that grey area as well.
But it seems that there is a lot of ideas being flung around. Some of this may be placed at the feet of Steinberg's push to have VST3 and the lack of support that came about for it.
As far as a roadmap goes, I find that X1d has answered a lot of concerns and ....well...may they carry on with X2.
