I had no problem getting an 07 Allstar right away about a month ago. I think the problem is that they fill all shop orders according to a pecking order then if a shop reorders a second batch it takes a while to get them in. So if you didn't snatch one up quick, you may have to wait or look for one on-line out of state.
As to the Superstars, my understanding is that the machining company that makes their molds totally screwed up and made a second star or shooting star mold instead of the Superstar mold. From info from BT, looks like Superstars will start shipping soon.
As to going with the Rocker series ahead of the star series, that made good business sense since JK wasn't perceived as a creek boating company but the updated Rocker series, which is a very good creeker, is going a long way to changing that perception and they wanted to get it out during "creeking" season, i.e., early to late spring.
