I personally think if only USA gets exclusives and the international don't, just don't have exclusives. What do they achieve with this besides frustration with their own fans? What do they gain by making exclusives available in certain areas? People rather just buy the darn things in any stores they walk into. All this does is give off the feeling to people these are highly limited and will likely never be restocked driving up the prices.
Blame US retailers? I dunno.
I'm in Canada and exclusives suck even more because we barely have Target stores.
