Breaking the release date has happened fairly frequently, but seeing as how Nintendo doesn't ship the games out until release day
I don't think that's true, for a few reasons:
#1: You can't ship games that quickly. You think they shipped the Wiis on the release date? You wouldn't get them until the day after the release date.
#2: I went to Future Shop (on the official Nintendo release date) and asked if they had it. They said it was in the back/storage room, but they couldn't give it to me, because the release date (for Future Shop) was the next day. I went to Wal-Mart the same day and bought it there.
P.S. It was in EB Games too.
Conclusion: It is possible to break the release date, but only if theres some kind of mistake with the staff/computer or something.
You can probably tell that I'm VERY bored....
