Even though the Xbox 360 version of the game doesn't hit store shelves until Wednesday, Microsoft has made available five pieces of content for Tiger Woods PGA Tour '07 on Xbox Live Marketplace. The content appears to be items that would normally be unlocked through game play.
There have been reports that EA has stated this content is still unlockable through normal game play, but by placing the items on Marketplace, those that want to acquire them quickly can do so for a price.
Thanks to Major Nelson for the content list.
