APF 2K8 reel editor now on XBLM, why?

An interesting item has popped up on Xbox Live Marketplace for All Pro Football 2K8. The item is a called the "reel editor." This item, as its name implies, allows players to create and edit replays in order to create personal highlight reels. Sounds pretty cool, right? We actually think it's a great idea. We have one question, though: why is this on Xbox Live Marketplace? Shouldn't this be an included feature in the game? Considering the game has only been out for a few days, we find it hard to believe this reel editor couldn't have made it into the retail disc. What's more, we're expected to pay 400 points for it? Sounds like unnecessary roughness to us.
