Xbox Live has been known to inadvertently leak stuff before it's supposed to, most recently with Halo 4 and the Karateka re-make. This time, it looks like most, if not all, of the holiday sales for games on Microsoft's game console. Now, these may not be the discounts coming to bunch of Xbox 360 but you should probably take a look just in case.
Twitter user lifelower found a bunch of Xbox.com pages—which have since been pulled—listing details like a free copy of the first episode of The Walking Dead. A post on NeoGAF collects everything. Here's a snippet below. Again, take this with a grain of salt. Guess we'll find out soon if these sales are the real deal.
