While only some aspects of tomorrow's expected Kindle and Kindle Fire revamp press event are known, some confirmation of rumors came in the form of an unexpected TV ad from Amazon during Wednesday's football game between the Dallas Cowboys and the New York Giants. In it, glimpses are seen of a new, brighter and backlit E-Ink Kindle Touch reader as well as shots of what may be the second version of the Kindle Fire. The ad could be seen as a harbinger of a major PR campaign around the new devices.
