current deal: upgrade to 16, get 17 FREE. Cool. 16 comes with a PILE of plugins.... so.... will all those plugins that come with 16 work in 17?
Plugins are not rocket science: make them within a standard and they can load into everything. They have to go out of their way to cripple them from working in the "next" version... .or Vegas coders are doing something VERY wrong.
* Plugins have worked this way for about 2 decades, this is not new tech
