Imo, Switch has great chances of taking November. We are already seeing great deals for the console and i'm sure Nintendo will have something for BF. That said, it will also get the first HD pokemon game, which even if it's not the one the core fans are waiting for, it will clearly have a big appeal. We will also be in the Smash hype, many people will take the console during a BF sale just before Smash instead of waiting the day it comes out. We also are finally getting some more "family titles". I think Labo and Mario Party will have some effect during Fall/Holiday season.
Sony will probably have similar deals as last year, don't think they can discount the PS4 more than that this year.
