Amazon took the 7 inch tablet to new levels with the Kindle Fire and in just nine months they captured 22% of US tablet sales. Amazon just announced the Kindle Fire is SOLD OUT. They don't state how many were sold, just that "millions of customers" made the "Kindle Fire the most successful product launch in the history of Amazon."
Amazon sent out invitations to the press for an event in California on Thursday, 6 September, and with this new sold out announcement I am now sure it will be for the Kindle Fire successor. There have been rumors of a larger Kindle Fire, but I would prefer to see a smaller one with nicer designed hardware. The first Kindle was a bit chunky and clunky and Amazon went on to make much better hardware so they can do the same with the Kindle Fire.
