Barnes & Noble's next ereader, the Nook GlowLight Plus, will be arriving shortly.
A reader has tipped me to news that B&N has leaked the name of GlowLight Plus on its own website. If you head over there right now and select the Nook dropdown menu, you will see a reference to a new Nook model:
"Nook Glowlight Plus" is very likely a reference to the B&N device that went through the FCC last month.
That device was tested for Wifi and had an estimated 6" screen, but unfortunately I am unable to confirm that the Glowlight Plus is the same device.
Clicking the Glowlight Plus link takes you to the product page for existing Nook Glowlight model, which launched in late 2013. The link will lead to the new device's product page once it officially launches, but at this time we don't know when that will be.
