I pulled this one off the Xbox site while looking for other stuff actually. They’ve announced the holiday bundle lineup, albeit somewhat discretely.

Holiday Bundles

•  $199, the Xbox 360 Arcade Holiday Bundle comes with six free games, including SEGA Superstars Tennis and five Xbox LIVE Arcade games.
• The Xbox 360 console ($299) and Xbox 360 Elite ($399) Holiday Bundles pair the consoles and the promise of the New Xbox Experience with two amazing games: LEGO Indiana Jones: The Original Adventures and Kung Fu Panda at no added cost.

So if you are looking at buying an Xbox 360 for someone you know you’ll be able to get them started right with a game to boot for no extra money.
