Rumors on Examiner.com suggest that the Gears of War 2: All Fronts expansion was briefly and accidentally posted on Xbox Live before being pulled back down again.

Earlier this evening, Microsoft had accidently made the Gears of War 2 expansion All Fronts Collection available for purchase. Soon after making the add-on available on Live and via the website, Microsoft was quick to fix the problem. Oddly, though, the add-on was also cheaper than originally planned. Perhaps it was just a mistake like making the expansion live too early.

The expansion is officially due to arrive July 28.
