The picture says it all on this one. Yes, on September 28, Amazon is set to announce a Kindle or its long-awaited Android tablet--or both.
We didn't get any hint as to what the product or products might be, but the invite did come from a PR person who in the past has sent out invites to Kindle events. That said, Amazon could easily announce a Barnes & Noble Nook Color competitor that falls under its Kindle brand.
Other rumors have Amazon announcing a touch-based e-ink Kindle similar to the Nook Touch or possibly a sub-$100 Kindle (or maybe both).
We'll be there in full force covering the announcement, so tune in to our live blog on Wednesday.
