Ah, looks like I forgot to mention back on March 1st that SS Starscream and SS Soundwave both showed up on the Target website, but only as online purchasing... which I guess made it difficult to have as a physical sighting. Soundwave has since shown up at EBGames stores, and maybe Starscream as well (both also showed up on Amazon Australia later as well, but again, these two seem to be stubbornly NOT showing up at national retailers).
After two false starts (listing it and then cancelling all orders, twice), Amazon Australia have finally had the SS-77 grey jeep NEST Bumblebee in stock, as of yesterday... but they only had a couple of units last night, so either they didn't get much, or they sold out very fast to people who check Amazon Australia very frequently.
(mine shipped today, after ordering it last night)
Meanwhile, wave 3 of the Classic Heroes Teams toys (now dropping the "Rescue Bots" logo) has shown up in Australia as well, with the new mould Optimus and Grimlock.
Not mentioned in this thread yet: Wave 2 Headmasters (Weird Wolf and Skullcruncher etc.) were sighted at a WA Target.
