Edit: According to one report, the new hardware is in stores this morning.
The listing is now visible to all, but it lacks specifics. We do know the new Nook Glowlight 3 has a 6" Carta E-ink screen with touchscreen and color-changing frontlight. It doesn't appear to be waterproof, but it does have the page turn buttons some of us want.
It also has 50 days worth of battery life and 8GB internal storage. Retail is $119, and it will ship on 8 November.
I generally have a low opinion of B&N but I must say this device is tempting. It's the only 6" ereader that I can buy with both page turn buttons and a color-changing frontlight. (Yes, Tolino has a 6" ereader with a similar frontlight, but I can't buy it here in the US.)
It is a little on the large side, though - the bezel makes the Glowlight 3 big enough that it is almost the same size as the Kobo Aura H2O, an ereader that only costs $40 more and offers a larger screen, card slot, and waterproofing (but no color-changing frontlight).
Here is gallery of product renders for you to feast your eyes on.
