At first I was like whoah, there's some fresh air in the actions of Nintendo, and I was just about to post this myself. Then I saw this thread and the information about region-locking, and now I'm like whoah, Nintendo tried to do something right but managed to screw it up anyway.
That said, I also don't appreciate Humble Bundle accepting region-locked stuff in one of their bundles. Might be OK in the store but not in the bundles.
