Microsoft will put a ton of effort into the Xbox One launch later this year, but that doesn't mean it'll neglect Xbox Live Marketplace.  In fact, Larry "Major Nelson" Hyrb just posted a huge blog update detailing what's coming to the service over the next couple of weeks, including some big titles, sales and more.

Let's start with Xbox Live Arcade.  This week brings Dungeons and Dragons: Chronicles of Mystara, Capcom's compilation of D&D arcade games.  You can get it for 1200 Microsoft points.  Next week also includes a trio of downloadable games, including Ubisoft's free Spartacus Legends, the role-playing Magic 2014 (800 points) and Doodle Jump Kinect (400 points).

There are plenty of deals going around as well. You can snag PopCap games for cheap, including Bejeweled 3 (600 points), Zuma's Revenge (400 points), Heavy Weapon (400 points) and Feeding Frenzy 2 (400 points), among older hits.  Next week, you can pick up some of Microsoft Studios' biggest releases at reduced prices, including Limbo (600 points), Sine Mora (600 points), Perfect Dark (400 points) and Fruit Ninja Kinect (400 points).

Finally, the Games On Demand service will see some love.  This week, you can download Gears of War: Judgment, Toy Story Mania and The Walking Dead: Survival Instinct, while next Tuesday brings the digital debut of Bioshock Infinite, Army of Two: The Devil's Cartel and Omerta: City of Gangsters.

Clear up that hard drive space – you're going to need it.
