This bit of news today might inspire Amazon to release real numbers tomorrow on how many KFs they sold. That would be a first for Amazon, yes, but just think. What if Amazon sold 7 million Kindle Fires last year. Wouldn't they want to take the opportunity to surprise everyone?
On the other hand, they might have just barely hit the 6 million mark (or maybe even fallen short), and that might be enough to discourage them. "Meeting expectations" is not enough anymore, so today's news might preclude tomorrows.
In any case, tomorrow's news is then one to pay attention to. Today is just tea leaves. Let's see what happens.
