"bwaaaaaaah! Yamauchi is racist! He's biased for Japan! *cry*"
Instead of pulling out this kind of frankly silly statement, you might want to try and use that gray matter you have between your ears (hopefully) or at least try and get your facts straight.
Japan got some of the chromeline cars we got in the collector's simply because they did NOT get them before. Yamauchi is SO biased for Japan that not only they didn't have the signature edition that Europe got, but their collector's edition is basically equivalent to the scrawny European one (it just got stealth instead of chromeline) with just the apex book and nothing else. So in the end they get no keychain, no die cast cars, no USB key, no certificate and all that. They also got no preorder bonuses.
On the other end Europe got the signature edition, and US got a MUCH fatter and more full featured collector's.
It's rather obvious why they didn't give away chromeline cars in the US and in Europe, considering that they were bonuses for the various collector's editions. if they did, people that bought those would obviously (and rightfully) be disappointed. PD ain't Turn 10, that pubblicized VIP status as exclusive and then sold it to everyone that wanted it, effectively voiding most of the advantages it gave.
It's actually quite funny that someone even expected it.
