You may luck out at a Target later in the day. There was a Target that unloaded some Wiis into the case around 5:30 (which fits my knowledge of my experience in the backroom of Target where we would pull merchandise at different intervals of the day, 5:00 being one of them)
Also EBs seems to get their shipments in the afternoon, 12-2, somewhere around there. YMMV on that, not sure if all EBs receive their shipments in that time frame.
