According to speculation on the Internet, Amazon is preparing to introduce two new Kindles. One will be an upscale model with a touchscreen--and maybe a stylus--and the other will be a basic model targeted at students.

In addition to the new Kindles, it's been predicted that Amazon will also introduce two Android tablets--a seven-inch and 10-inch model--based on Nvidia processors. The smaller model will reportedly sport a Tegra 2, while the larger model will feature a new quad-core Kal-El. These slates are expected to be released in time for the holiday shopping season--but this is still just a rumor.
