These leaks happen all the freaking time.
Really? Gee, tell me more.
Who DOESNT have leaks now adays, the entire plot and outline of Dmc and Dead Space 3 were leaked a week before the release
Stores breaking street dates isn't really a problem of internal security.
I personally don't see anything wrong with it. I mean if anything it's better than having to wait a few days extra and breaking your head wondering what's in the next issue.
