Since the PS3 was technically ON SALE (See CEO Statement re: sales brochures and marketing activities) more than one-year prior to the filing date, I think you need to look up "on-sale bar" - which if it doesn't come up in examination, I am *certain* it will come up in a re-exam.
Hold on to your donuts, oldsters.
