Last night, we got a tip telling us that this morning, Barnes and Noble's ship date for the Nook would slip further -- from the previously known date of January 11th to January 15th. And hey, what do you know? The BN website is now showing an expected ship date of January 15th -- though it seems this would be the shipping date for new pre-orders, not for pre-existing ones. Disappointing for all of us who are expectantly awaiting our units, no doubt, but there's the possibility of further bad news. The last time we checked in, the Nook was expected in some Barnes and Noble retail stores on the 7th of December. This tipster, who as we've just mentioned proved spot on with the expected shipping date (and whose name we know, though they've asked us not to print it), also says that no Barnes and Noble stores will have actual Nooks on hand until after Christmas. Of course, we have no way of knowing if this information will turn out to be correct, but at this point, we thought it seemed a decent enough piece of "possible" to pass on.

Update: We've just spoken with a Barnes & Noble rep, and they say they will have the Nook in select stores on Monday, December 7th, so we're just going to have to be patient and see.

Update 2: If it was not clear enough, this new date of January 15th (as well as the previous date of January 11th) seems to pertain ONLY to new pre-orders of the device -- not orders placed before the initial run sold out.

Update 3: And the in-store delay is official... Barnes & Noble is now confirming that the Nook will NOT be available in stores on Monday, as it's "intent on fulfilling earlier preorders."
