Perhaps. But don't you think they can put out a press release that would be covered by every major newspaper, online and offline? Or Bezos could give an interview with the WSJ, NYT, or anyone he chooses. Why would they leak it CultofAndroid.com, a second or third tier niche tech blog?
I usually don't go for the conspiracy theory. But my first thought after reading the stuff about the Fire was that I should probably get in my order for a second one soon if I want it to show up before the holidays.
Although leaking the other Kindle data doesn't seem as convenient.
