Because Spain is awesome? (Batman and Constantine in the DVD-era, Mirror's Edge PS3 Steelbook)
Seriously, I don't believe after decennia of milking the Star Wars cow, new owner Disney will end this tradition by only releasing this in an almost bankrupt country.
Easy tiger, Spain still a strong market and Amazon.es dispatch WW so we all can order from there. However I think that will end up getting released everywhere.
They don't even bother to mention which version it is on the front (special edition, Lucas' CGI diarrhea-recut edition, no-you-won't-ever-get-the-original-edition)
