Well, that's certainly disappointing to hear, but thanks for responding!
I've been a dedicated GK user for *decades* now, and absolutely love my (2) 800RBs and my 400RB. But as I'm getting close to 70 years old, the process of downsizing my rig is getting more and more important. When I heard that the Plex could duplicate the sound and tone of the 800RB, I began thinking about moving to a pedalboard-based rig, and the Plex would allow me to leave the much larger 800RB at home, and adding it to a pedalboard that fits into a trunk-on-wheels (which I already drag around with me anyway) is very appealing! ;-)
I still have my sights set on the Plex, and will save space for it on the new pedalboard I'm currently designing, simply because the size and weight are still major benefits to me at this point. But it's disappointing to know that I'll probably still have to use the separate GK power supply instead of having a fully-contained and powered pegalboard rig. :-(
Anyway, thanks so much for the update!!
