So I wound up getting the car yesterday. It does have the "F" revision battery pack, it was officially built February 3rd, so it seems like it should have nearly all the same hardware creating the efficiency gains in the LR+, but something about my particular battery pack's management system means the firmware can't be upgraded to officially become a LR+. Getting the wheels I wanted (without dealing with a swap and another 4-6 week wait for a new car) is worth it to me. As I said previously, the car was what I ordered and I'm fine with that... I'm not the type that would rather wait endlessly on rumors or tiny gains. I would certainly love to have the LR+ after having waited an additional 2 weeks for 0 reason in the end, but not at the expense of the wheels and an even longer wait! So I suppose "annoyed" with the process is the best way to describe my experience.
