Yup! I'd love to see whether anyone who calls actually gets a meaningful response from them. My guess is that they won't say anything meaningful and will urge everyone to be optimistic.
My theory is the "highest priority" people are folks who would have received As earlier in the cycle, but they literally ran out of As and are afraid to be overfilled, so they jump these people to the top of the list, and let them know it, because they don't want to lose these people to early commitments elsewhere, since they are very likely to be called.
If I'm right, this would explain why they don't go back and give the designation to people who were high priority earlier in the cycle. As for everyone else, if they have "normal" movement people will still be called, but there is no way to know how many until it begins. The bad news is that the ratio of high priority to regular, and even acceptance, is so out of whack that it seems like the majority of post-II decisions are HPWL. If true, that would make the odds of receiving a call pretty low no matter how many people they call. And yeah, unfortunately, that makes regular WL a R.
