I'm curious about this as well. I would assume that there's two types of applicants in terms of probability of acceptance: those who received interviews and those who do not (throughout the entire cycle). This early in the game, I don't think there is a preference for, say, September versus November interviews. They have a few months to compare interviews before making finals decisions. In fact, one can argue that having a later interview would help (as it would be closer to "decision" time), but that's probably just a myth as well.
