The release of the first wave here is getting closer, as the Deluxes and Voyagers have now been found at US Retail stores (after the advance release of the Deluxes last month through HasbroToyShop).
The Deluxes are Bumblebee, Stinger, Crowbar and Ratchet, while the Voyagers are Optimus and Starscream.

Take note of the prices though, as the Deluxes were US$25/27 and the Voyagers US$37... which is significantly more than the price point of Deluxes and Voyagers in the mainlines, and would translate to about AU$45 for the Deluxes at retail here, and about AU$70 for Voyagers at retail here (based on the price differences of those size classes in the past). They will be slightly cheaper at Walmart and Target in the US, but not by too much, as the prices for Deluxes have been going up a lot in recent years.
That means that even if our prices are bumped up to $35 for Deluxes, it is still cheaper than in America (at the current exchange rate), and way cheaper than what a US$25 toy usually gets sold at here in AU$ from Hasbro Australia.
