In this age of open access to information and poorly-guarded secrets, we get a startling amount of information from leaks. They happen all the time. Rarely do products actually make it to their official unveiling without a good chunk of information spilling out beforehand. Leaks are incredibly common. What's less common, however, is when separate leakers butt heads, which is what's happening with the Pixel 2 and the Snapdragon 836.
Those reports, from XDA Developers and Android Police, claim that the Pixel 2 and Pixel 2 XL will likely use the Snapdragon 835. Furthermore, a recent FCC filing for the Pixel 2 pretty much confirmed that the smaller handset would indeed use the 835.
That's not necessarily the end of the story, though. Although the 835 story seems rather definitive, Blass commented on his original report with the following:
Re: SD836, I haven't heard anything further since my initial tweet, and since the source has proven accurate time after time, I stand by it.
Over the years, Blass has been an incredibly reliable source of information; he wouldn't be held in such high regard if that weren't the case. If this were any other leaker, I'd chalk it up to a bit of misinformation and call it a day, but in this particular instance I'm curious to see exactly where the truth lies.
