Barnes & Noble may be selling millions of Nook products, but it's sounding like the 3G variant hasn't really done its part to help those figures. We've received hard evidence from within B&N that the Nook is being discontinued, with sales to seemingly continue until stock is exhausted. The outfit is encouraging retail partners to not send out any "bulk requests" for the Nook 3G, as there simply "will not be sufficient quantities to fulfill those orders." Of course, we're told that the company never actually received a huge amount of Nook 3G bulk orders to begin with, so maybe WiFi really is everywhere these days.
