We recently reported that Amazon is set to unveil an update to its line of Kindle ebook readers sometime soon, and now it appears that the date for everything to go down will be September 6. Amazon has sent out notifications of a press conference to be held in Santa Monica, California where we expect that we'll see the next version of the Kindle Fire as well as updates to the Kindle e-ink readers as well. Things kick off at 10:30am that morning, and of course, we'll have all the news right here.
