My brother and I got there at around 7 AM (PST) and were 8th in line to get our Wii's. The Torrance California Target had 50 units in stock.
Got the Wii and was really impressed by it.
BTW, I dont suppose there is a way to measure signal strength on the wireless connection?
I used to work at Bestbuy, and having the games acutally hidden? Probably not. BB and CC use similar systems to inventory their merchandise so, if you asked an employee to look it up in their inventory system, it would show the game(s) being there, assuming they were being hidden.
