Staples (SPLS) president Demos Parneros has gone on record in stating that Amazon (AMZN) has plans to introduce as many as six new Kindle Fire tablets. Reuters on Monday reports that Amazon has plans to add up to five or six new tablet SKUs to its lineup. According to the report, Parneros confirmed that the Kindle Fire tablets will vary in size, and will include at least one 10-inch tablet model. BGR exclusively reported last month that Amazon is prepping at least two new Kindle Fire tablets, a new 10-inch model and an updated 7-inch tablet with a redesigned case. A separate report suggested that Amazon will launch new Kindle Fire slates early next month.
