Well, the way I see it, If everyone had access to a zip file that contained all the RTAS plugs, then, you could manually install them even if you were to be running 10.x. What will definitely kill us is if they no longer support RTAS, which would piss their user base off to no end. Even though I use this every day, I'm watching the same decline as you are. My hope is for Logic X to have some accessibility improvements. Then, I could sequence in Logic, and track audio, edit, mix, etc in Pro TOols. Everything all remains to be seen.
