For my money there were the Two Avengers sets put out to coincide with the first movie (albeit mostly repacks, but with three solid exclusives), the elusive Future Foundation 4-pack and the Classic/Modern Heroic Age sets which (I think) shared shelf space with specialty shops. Other than that, the Peter Pan line is the only other Minimate representation to have gone through Disney Store shelves.
I just thought it might be worth bringing up again thanks to DST's new Star Wars busts, banks, and bottle openers, maybe there's a better chance of some minimates.
