It's unfortunate that the US is getting the shaft not getting the actual Anniversary Edition with the steel case and all. I know it doesn't add anything to the game itself, I just don't mind spending the extra dough to get extra stuff when it comes to a game that only releases a sequel every few years.
I just don't believe you won't be getting it, especially if the Australian affiliate is

On a side note, I'm just checking FMOI, pre-order the GT6 AE get 5+5+5+5+6 cars, pre-order standard GT6 and get 6 cars, buy GT6 after launch you get no cars. That's what the site is saying yeah?
