So, it's beginning to look as though FUNi flat out lied to eveybody about the Wal-Mart listing being false now that another site (much less RightStuf) has it listed, with MagicBox suggesting that FUNi is pleading ignorance (i.e., claiming they really didn't know about it at the time, and were "caught off guard" as it were). Still, if FUNi did li to us, then that would indeed mean that Wal-Mart leaked something they weren't supposed to...
However, I'm beginning to think that the initial response may have just been a more "polite" way of saying "Look, could you not bother us with this right now? We already have enough problems." Of course, that's complete conjecture on my part. Still, I refer of course to the One Piece streaming issue, which last I checked still has yet to be resolved one way or the other.
Personally, I'm hoping FUNi doesn't go ballistic and start asking us to choose between "Dragon Ball Season 1" and "legal One Piece streaming". Still, if it did come to that, I would choose the Dragon Ball set since that was the show that started it all (back when FUNimation was a completely different company). In any case, that's for another topic, actually.
Suffice it to say, it would now seem that Anime Expo is when we'll know once and for all what's going on (I hope).
