List isn't entirely complete, as I've been selective in regards to which figures I've been getting. Hopefully someone can fill in the blanks amongst the leader and legends class figures I've skipped (Thundercracker (leader), Thundercracker (legends), Viper, Windcharger, Huffer and Warpath). I don't think there's any difference in the UPC's, but the wave 1 deluxes are the multilingual versions with collector cards, and waves 2 and 3 are the comic packed english versions.
