Since MightyApe (located in NZ) have the three wave 5 Cyberverse Deluxe toys in stock (Soundwave, Starscream, Prowl), it means that the stock came from Australia, and should mean they should show up here... if any retailers here still want them (or if Hasbro Australia didn't send all of the shipment to NZ).
They are AU$35 each, which is mid-range to what they are at retailers here ($29-40), but have a shipping fee, which is only $5.90 to Australia.
