I agree that you lose a lot of coverage on mainstream news sites by announcing a new console revision the same day as (literally minutes after) iPhone 7 but I don't think iPhone 7 is going to steal a lot of its exposure on gaming sites.
PS4 Pro seems to get the spotlight on many sites so I think they're fine. Consoles only reach mainstream media when a new generation of hardware is announced anyway.

PS4 Pro has just been added to Amazon for preorder. If that does well, I don't think Sony will have many regrets
