Amazon said today that it has sold all of its Kindle Fire tablets. The device launched in November 2011, and the retailer claims it has 22 percent of the U.S. tablet market.

Amazon has scheduled a mystery press conference next week, most likely to reveal some new devices. According to AppNewser, some believe that Amazon will release several new Kindle Fire devices in different sizes.  Business Insider speculated that Apple has been developing the iPad Mini specifically to compete with the Kindle Fire.

Founder/CEO Jeff Bezos had this statement in the release: “This has been a big year for digital products on Amazon—all of the top 10 sellers on Amazon.com since Kindle Fire launched just less than a year ago are digital products. Kindle Fire is sold out, but we have an exciting roadmap ahead—we will continue to offer our customers the best hardware, the best prices, the best customer service, the best cross-platform interoperability, and the best content ecosystem.”
