I just got an invite at 1:45pm PST and am up and running as of 2pm.
Install was easy.
Here is a populated C3
Green highlights installed items. You can hide products by right clicking - which I did with Dimension Pro, but I have not been able to get it back.
New splash screen
Unfortunately my work today is sound design within Omnisphere so I might not get a chance to run through everything, but I will try post some more info later.
First thing i have noticed is that there is now an FX on/off button and an add fx button in the FX bins. No more right clicking to bypass or bring up the insert menu. Nice!
