I appreciate you making this thread, because I've been considering the purchase of another 11R just to get PT11. It NEVER dawned on me that I wouldn't be able to edit 11R on it; and I am clueless when it comes to operating 11R from its controls.
The main attraction for me is - at least according to the Sweetwater catalog that arrived today - is PT11 can bounce 150 times faster than real time, meaning it can bounce mixes that are too big for one's computer (I'll admit I've run into that conundrum on more than one occasion!).
You will get two versions of PT if I understand this correctly. PT-10 (10.3.7 is the latest) will allow 11-Rack editing via on-screen embedded functionality. PT-11 will only allow changing from one Rig to another. Kind of bites, but it's not a huge concern for me personally. My 11-R sits directly to my left at shoulder level. No biggie. Besides, one should learn the onboard GUI in case they ever need it. At least that's what I tell myself. LOL
