Update: Microsoft has made the price cuts official and the games' lower prices appear in Xbox Live Marketplace.

Original Story: Microsoft will be adding three popular Xbox Live Arcade games to its Arcade Hits collection, giving price cuts to downloadable versions of Ultimate Mortal Kombat 3, Worms, and Feeding Frenzy.

The Arcade Hits website was recently updated with the three games and lists them all as retailing for 400 Microsoft Points ($5).
