I love how you'll now try to argue that "tests sites" are somehow legitimate experts because their conclusion fit's your shill game.
As people like Thomas Hogan point out Nikon is good at improving AF by firmware updates over time - and Sony tends to stick in a time warp - indicating if there was any truth in this claim it is less true now than in 2017.
Let's not confuse ambition with reality. Nikon is good at attempting to catch up to the competition through firmware updates. The "hopeful firmware updates" are a great tactic for keeping customers on the hook, and not much else.
And no disrespect to Thom. From what I've seen from his posts here, he seems to be a good guy, and I do agree with a lot of his opinions, but the situation is simply that... he's another guy with another opinion, just like the rest of us.
