Further proof that the Americans aren't going to get anything new released until August - Hasbro website has listed an official release date of Leader sized Starscream as August 9th. A very specific date, suggests that they definitely don't intend to release the mid-year range any earlier than August.

Good news for us I guess, as the lower-than-expected prices of PCC and Deluxes in some stores could actually make it worth buying up and exporting them to desperate Americans. (their RRP of the 2-packs is US$10 plus tax, which is a bit above AU$12 at the current exchange rate - but our cheapest price of AU$16 at BigW is about US$13 - that's close enough to be 'worth it', but then you have shipping which would effectively double the price)

Based on those calculations, the recent drop in exchange rate makes this the closest we've ever been to the converted Retail price of the toys in America.
