B&N Searches Bring Up E-books First Today

I'm not sure how long this has been the case -- or if this is the result of a deliberate change, or some glitch -- but this morning, on all of the books I'm looking up at BN.com, the e-book edition comes up first, with the print book afterward.

It's an interesting, if odd, development -- does B&N think consumers will accidentally buy the e-book and become so enamored of the format that they then immediately buy a Nook?
