No question: Amazon has new Kindles on the horizon--their State Dept contract says so.
Now, *when* they arrive is where the guessing game goes.
The original widespread guess was July but it was followed by a report of production problem with the frontlight leading to a delay, generally guessed at 1-2 months.
So a mid-to-late august announcement isn't all that unlikely.
And with both Amazon and Best Buy having sales on refurb'ed Kindles in the last week or so, these new reports add fuel to the fire.
Besides, we need new toys to talk about.
