I stopped by one of the showrooms today and had a chat with an advisor there. It sounds like there is a handful of Performance-trim MYs in the area that are "on the ground," which apparently means someone could take delivery within a few days, though you won't be able to see it before ordering. All were older VINs, pre-taillight update. At least one is a sleeper and another is a "fleet car," meaning you get about $2,200 knocked off the price because it was used for test drives (that one has a 22xxx VIN, meaning it was built quite a while ago).
Tl;dr: if anyone is getting really desperate, you can get your fix now.
