Amazon is expected to announce a new Kindle Fire 7-inch tablet at its press event in Santa Monica, Calif., on Thursday at 10:30 a.m. PT. What improvements can we expect in this year's model? Will Amazon reveal a larger 10-inch tablet to more directly compete with the iPad? If Amazon is to stay competitive with Barnes and Nobles' Nook, it will have to introduce a new backlit e-ink Kindle tablet, too.

Macworld editorial director Jason Snell is joining Melissa J. Perenson for live coverage of the Thursday, Sept. 6 press event. They'll have all the coverage of whatever Amazon announces when the event starts at 10:30 a.m. PT.
