The weekend is over, let the next-gen console wars begin! Nintendo rolled out its Wii on Sunday, selling out allotments in numerous occasions, but the craze was nearly not as bad as Friday when people got mugged, stabbed or even shot at while waiting in line for a PS3. While a mere 400,000 units were shipped to stores across North America, USAToday claims Sony will airlift up to 600,000 more units by the end of the year, though it hasn't announced where and when.
