Wow!? Wednesday is Xbox Live Marketplace day.? I always, like many other 360 owners, check out the movie section to see if anything cool was uploaded.? To my surprise, Pirates Of The Caribbean:? At World’s End is now available for rental on Xbox Live Marketplace in HD.? I’m starting to believe that Microsoft is trying to take out Blockbuster and Netflix.? I don’t however, think that they are trying to sabotage the HD disc market.? Blu-Ray and HD-DVD are doing that themselves.
