If crowd at my Best Buy and Gamestop are any indication, XBox One is in some major trouble.
GameStop: PS4 launch was over 100 units and a huge crowd by 11PM. I didn't stay through the launch for XBone since I didn't have a console, but there was no crowd. Just five dudes in camper chairs and one guy in the store. I flipped some Slim AC Adapters and left. It was a sad sight.
Best Buy: Swung by on the way home to see if the crowd was any better. Small pre-order line (~20 people) and a second line for folks getting tickets to buy systems. They were still handing out tickets so I got in line. By 11:45 they were STILL giving out tickets. Sounds awesome, right? Lots of stock! But no. They only had 44 units to sell though. Don't think they even managed to move them all tonight. I'll probably return mine since I was mostly hoping to flip. At least the guys in line were cool.
