Sure this has been beaten to death elsewhere, but the upgrade to X3 has so many neat third party plugs, it is an excellent deal if you don't need to use them in other DAWs.. And know that the licensing for these things has to be passed on if the company is going to make a profit and stay solvent.
Microcosm of a guy like me is that I already got all the legal and registered versions and beyond of the Sonar limited plugs.
What's in it for me???.
Still can't chain more than one synth on a track any more than Sonar 4, begging the company for years to fix this. Appologists will point to a convoluted process to clone this and that to open a fleet of channels, and then we will be almost to where Reaper is.
$200 was the brick wall of passing on an upgrade to support buying into restricted versions of what I already have.
Black list me as an apostate, but passing the generous 200 buck upgrade until maybe Sonar X10 or later if Gibson doesn't make a mess out of things.
May all be well,
