She also said October. That's extremely unlikely now unless it's treated like a normal Direct with 2-days' notice. I don't see a reveal happening this year. If I'm right, I'll have expected it. If I'm wrong, I'll be surprised. I'm done, and frankly I'm not really all that hyped at this point.
Nintendo does announcements on wednesdays and thursdays as well. ANd yes, there are Pokémon news on thursday. But that is no reason not to announce an reveal event.
I think it's still possible Nintendo wants to announce the event exactly a week before the actual reveal.
Honestly we don't know. It's still early in the second week of october. Expecting a delay is still too premature.
