Plummeting revenues be damned, Barnes Noble still isnt giving up on the Nook. The books retailer plans to release another color tablet this year, according to CEO Michael Huseby. But the next Nook wont be built by Barnes Noble itself. The company is actively engaged in discussions with several world-class hardware partners related to device development as well as content packaging and distribution, Huseby said in a statement alongside BNs quarterly financial report today.
