You sais US only, i'm from Canada, hope it doesn't bother you too much...!
I was told by MY dealer (who didn't order any demo), that he would instead receive a TRI for his launch event on April 27th-28th. And since that is my TRI, I could probably pick-up right after the launch party, meaning April 30th.... They also told me there were 3 dealers in the same situation across Canada...if this happens to be true, I'll be one of the few riding a TRI, or any Panigale for that matter, in Canada next week...
Still waiting on a concrete confirmation from my dealer though, and "D" day is getting very close.
