Read this item in today's paper that Costco is replacing it's unlimited return policy for electronics with a 90-day return window instead and extending one-year manufacturer's warranties to two years at no cost. The company stated that customers were essentially "trading up" plasma and LCD TV's as prices fell and features got better. The new policy is going nationwide in April; it's already starting in California. Not sure how this affects prior purchases, but a heads up to anyone who planned on trading an old 360 for the rumored black version.
