The news yesterday that the PS4 would cost US$399 was met with applause… followed by consternation that the Australian list price was $549. That always left importing with a direct shipper open as an option, but you may not have to go down that route, as it appears that Amazon might ship you one for the US price.
I've got to say "might" here, because while it appears that the PS4 doesn't fall foul of Amazon's own rules regarding regional availability -- where there are some products they specifically list as shipping only within the US -- it's still only at the stage where they've listed it as a product they'll sell at some point.
They don't even have a price up as yet.
No doubt a firm as large as Amazon might be able to wangle some kind of special pricing, so it may even be lower than $399. It's a promising sign, especially as the PS4 will be region free, but bear in mind that Amazon has a bit of a history of cancelling orders prior to shipping. Still, US$399 plus shipping will easily beat $549 unless the Aussie dollar collapses spectacularly in the meantime.
Thanks to Lachlan for the tip!
