The Xbox 360 forecast is absolutely droughtful this week at retail, with the Clash of the Titans theater DVD release tie-in drying up store shelves. Thankfully, the Xbox Live Marketplace is overflowing with new content this week, including today's release of the new Madden demo.

Additionally, DLC for a pool of recent releases -- Alan Wake, Lost Planet 2 and Transformers, to name a few -- flowed out today, and the "Summer of Arcade" shines on tomorrow with Hydro Thunder Hurricane. (Did you read our review yet?) Finally, Borderands' trio of add-ons is on sale through Sunday.

Check out complete details of the week's XBLM content after the break.
