It could. They just wouldn't go up for PO so fast. Remember, this is an Aou version not a CW version. So they have had the reference stuff for two years.
Also, when they are sponsored like this, for a show, part of the cost of the figure is offset so they don't need a long PO period to gauge interest and allow for retailers to decide. It's a limited release so that part isn't necessary. Otherwise this would have gone up PO 6-8 months ago. Or not be ready for that long. It's also just a repaint essentially with new tailoring. Like red snapper and mkvii and 3 stealth ect..which where available at shows immediately
