It should still be through Hasbro Australia, but in the past when EB have really limited stock, they don't list them until they have the units in-hand, to be sure of the quantity and not over-sell them.
It is possible that Hasbro Australia got their hands on this small amount of stock at the last minute, and offered it to EB, instead of Kmart.
I didn't hear anything about this one, but this time of year is really busy for a toy company, so I often don't have much interaction with Hasbro during the christmas period (or hassle them with questions).
I bought mine from OMP, and it is still on its way to me at the moment... but fingers crossed EB (or even Kmart) get the wave 2 Voyagers for me to complete the second wave.
