You're right of course -- people who behave like animals over a video game system are the ones to blame -- but why is that manufacturers can never make enough of the hot new, must-have Christmas gift item? Whether its a toy or a video-game system, this happens almost every year.
I'm not advancing some conspiracy theory here, but rather I am honestly wondering about this.
It can take a while to get a manufacturing line running. New, high-tech devices as especially bad; it's very expensive to build the fabrication processes sometimes, and the companies want to rush their product out by Christmas because that's where all of the sales are.
The reason they don't is because the system always has problems with it. It's pretty much a beta testing of the PS3 right now...peoples will break after they spent 3000 dollars on it and they will have to wait to get a new one which most of the bugs will be fixed.
