In the words of Glenn Beck callers, “Awwwhhhh Yeeeaaaahhhh!” Costco has the 360 bundle available to order online. I know I’m going to get it when I read these little words: “Backwards Compatible: top-selling Xbox® games can be played on Xbox 360â„¢, including Halo® 2.”
***UPDATE***
Costco has taken the page down. Don’t know why, but you can see if it’s back up here.
