According to Graeme Boyd (aka Aceybongos) Xbox Community Manager, Europe, if your Xbox 360 gets broken after tomorrow, you're going to have to wait until after Xmas for repair.Here are the exact
words:
"From the Xbox Support Team: If you're getting your Xbox repaired tomorrow is the last day for pick-up to get it back before Christmas."
So, fingers crossed that yours doesn't blow a gasket.
