I doubt that.
Sideshow has a habit of putting things on waitlist to prevent people from using discount codes, or to trick people into pre-ordering because they think it'll be gone soon, while there are plenty of them in-stock the whole time.
Like their "Less than 10 remaining!" alerts, which, somehow jump to "Less than 50 remaining!" the next day.
In the past few weeks there have been like a half a dozen people getting on the waitlist and having it convert within a few days, including myself. That's way too convenient.
