"It is typical for Apple to hold up to four events per year: one in the spring, WWDC in June, the fall iPhone event, and a fourth fall event that's Mac and/or iPad focused." - MacRumors

They have held an event in October or later in 8 out of 12 years since Tim Cook took over. https://en.wikipedia.org/wiki/List_of_Apple_Inc._media_events

Just a press release doesn't count, but if they announce a video ahead of time and play it live (even if there are no in-person participants), I will resolve this as YES.
