I also went to check several BestBuy around my area, no dice either. I noticed BestBuy tends to do this for these less publicized games. They didn't have GrimGrimoire and Odin Sphere for a full week after the official release date.
I strongly believe that they are doing this on purpose to avoid people price matching those first week release sales. FYI, Fry's Electronics are selling Culdcept for $37.99 starting Thursday afternoon. Yeah, it's just 2bux off, but it's better than nothing.
