As a web developer myself, I know this is one thing you don't do. It seems a
hacker has gone and grabbed a number of box art from
Xbox.com with many games that are unannounced. My question is to whoever set this up, why would you even put these images on the production site for someone to find out about? If anything, there should have been a prep site for these to live on until you are sure you can publish them. Hiding them via obscurity doesn't work, but their mistake is your gain as you can now see a lot of new games coming out for the Xbox 360.
