I'm still puzzled by the whole thing. At least on Amazon UK, all Kindles except the Paperwhite Kids and the Scribe have been out of stock for days (weeks?) now, and so far our best intel on the new devices point to a basic Kindle with a slightly brighter screen and a Paperwhite with a slightly larger screen.
Those updates are welcome but not revolutionary, and hardly justify Amazon losing sales every day in preparation for their release.
I guess as
pdurrant said, we'll just have to wait and see!
