Interesting time for the event: It will be at 1pm on the 31st of October (local time).
The rumours say we will see new MacBook Pros with the new M3 Pro and M3 Max chip, but that there won't be any updates to the MacBook Air.
There are also rumours that we might see an updated 24" iMac with an M3 chip, which would be nice since it hasn't been updated since it was launched in 2021.
