Why am I the only one who sees this?
It's just the way Tesla operates. Model S priority was given to "Roadster friends and family". Obviously, people on the wrong side of this are not going to be particularly happy about it. On the bright side, Model 3 owners will probably get first dibs on the Model Y, pickup truck, and new Roadster.
On topic, I don't think this will affect short term price movements in any way.
