As our sources had already told us, Microsoft confirmed a second Kinect bundle that will be available this holiday season that will offer a hard drive. The second bundle will join the already announced Kinect bundle that includes the Kinect add-on, along with the Xbox 360 slim with 4GB of flash memory on board.

The hard drive bundled version will feature the same 250GB hard drive installed in the Xbox 360 console, along with the Kinect add-on. The package will be sold for $399, which is a $50 savings over buying the console and the Kinect add-on separately.

Like the first non-hard drive Kinect bundle, it will include a copy of Kinect Adventures as the pack-in title. The hard drive Kinect bundle will arrive on retailer shelves in North America on November 4th.

Our sources claim that the hard drive version of the Kinect bundle may only be available during the holidays, after which it is expected that Microsoft will move to offer only the lower-cost bundle package going forward.
