Consumers aiming to buy Amazon's current Kindle Fire are out of luck, but a new model may be just around the corner.

The retail giant said today that its popular tablet is officially sold out after becoming the top-selling product since its debut almost a year ago. Amazon wasn't shy in bragging about the Fire, calling it the "most successful product launch in the history" of the company, one that has garnered more than 10,000 5-star customer reviews.

"Kindle Fire is sold out, but we have an exciting roadmap ahead," Amazon CEO Jeff Bezos said in a statement. "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."

That roadmap is likely to include the Kindle Fire 2, which Amazon is expected to announce at a new product launch event on September 6.
