Amazon has announced they will hold a press conference on September 6. They have not said they will announce new Kindle and Kindle Fire models, but speculation is rife throughout the web! For one thing, both the Kindle Touch and the Kindle Fire are sold out. Everyone assumes this must mean that new models will be coming out to replace those entries in the Kindle lineup. It's also interesting that the bare bones (non-touch screen) Kindle is still in stock, as are the Kindle Keyboard wifi and 3G version, and the Kindle DX.
This suggests Amazon is planning one or more replacement Kindle Fires. What could be different in the new Fire? Perhaps a larger screen, but I think a 3G or 4G connection is more likely. For the Touch, I would expect Amazon would have to come up with a front-lit model to compete with the Nook with Glowlight. The question is, would there still be a non-front-lit option? Another possibility is a dual screen, e-ink and LCD tablet, sort of a Kindle Touch/Fire hybrid. That would be totally cool!
We'll all know come September 6. The event will get a lot of coverage, including live blogging by The Digital Reader blog. Unfortunately, the press conference is in California, so us East Coast types have to cool our jets on Thursday, until California wakes up and gets on with it!
