I'm fully in favor of this.
I mean, it's pretty clear they already do regional pricing, when it means they can make more money...
I've been paying in euros since day one, which really just means we Europeans have been paying more than Americans have since day one.
Rather than, as a certain someone on this thread is doing, claim all americans should pay 14,50 $ (the equivalent to 12,99 €), I am, rather, demonstrating that regional pricing already does exist.
Of course, I wouldn't mind if they decreased prices in Europe (in the name of fairness, right?), but likewise I wouldn't mind if they decreased prices in other nations where it would certainly make a difference to the paying customer.
Why there'd be people upset that those in less fortunate places than us be allowed the same opportunity to enjoy the things we do, I will never understand.
It is rather... repugnant.
