Microsoft will be heavily promoting their Xbox 360 HD-DVD add-on this holiday season, offering the same deal as Sony has had for its Blu-ray competitor. If you buy an Xbox 360 HD-DVD add-on from now and until January, you can get five HD-DVD movies for free by mail. thirteen titles are available to chose from, and include:

Serenity, The Chronicles of Riddick, Hulk, Children of Men, The Fast and the Furious: Tokyo Drift, Troy, Full Metal Jacket, Corpse Bride, The Prestige, Swordfish, Black Rain, Dreamgirls and Word Trade Center.

Pretty sweat deal, as the movies are somewhat newer than the ones Sony offered earlier this summer. The HD-DVD add-on retails for $199, but several retailers (and e-tailers) have it at a lower rice, usually in the $170-$180 region.
