Amazon is to introduce up to five or six tablet SKUs, or stock-keeping units, according Demos Parneros, president of U.S. Retail for Staples Inc, which sells the Fire.
The tablets will be different sizes, including a 10-inch model, Parneros said. Amazon spokespeople declined to comment on the company's plans.
Amazon has long been rumored to be expanding on its foray into tablets with 7-inch Kindle Fire.
Brandon Watson, director of product management for Kindle Cross Platform, says "I can't really say much about some of the things on which I am working. I can say that the goals of some of the teams are huge. Huge."
He also noted that while being recruited he was told "the goal of Kindle was to enable a system to allow someone to buy any book ever published, and have it delivered anywhere in the world in 60 seconds. It's time to think bigger."
No word yet on when Amazon might be planning to unveil these new tablets.
