I work at a Gamestop and our store Point of Sale system hasn't updated to show this yet, but it's kind of odd so I thought I'd mention it.
The gamestop.com site is already shipping out this particular DVD set where most other sites have a pending ship date of March 9th, (though it wouldn't be a first, I remember when Rightstuf shipped out one of the Piccolo Jr. sets about 3 weeks ahead of the projected original release date).
Anyway, just thought it might be useful info for someone without any patience.
