Every leak counted here revealed something Google had not announced about a product: a device, feature, price, timing or project status. Kamila Wojciechowska broke 47 of the 487, and Mystic Leaks 39. Google's beat runs through a small number of Android specialists rather than a single dominant reporter, which is a different shape from Apple's, where one name holds about a third.
A beat with specialists, not a single voice. 63 named sources produced 487 leaks, and 34 of them appear exactly once. Google Google reporting comes mostly from Android-focused outlets and the people who read Google's own app code, with regulatory filings and retail listings filling in the rest.
Why that matters for reading any one leak. A great deal of what is known about a Pixel Watch before launch comes from software teardowns, which are unusually reliable about features and unusually quiet about prices and dates. Read the source's beat, not just the byline.
What one leak means. One leak is one substantive revelation about one product by one source. Not one fact: a report giving a watch a new chip, a new battery and a new size is one leak, not three. These 487 leaks contain 846 separate checkable claims, and each row below says how many it holds.
The same rule for every format. A source earns one leak for each product about which it reveals something genuinely new, whether that arrives as a newsletter, an app teardown, a social post, a retail listing or an obtained document. A later article counts only where it adds a new revelation rather than re-explaining the same material.
