There are EMH times posted on Intercot for October, but I'm not sure how accurate they are. There is also a post on the big "October Hours" thread where someone had been told different EMH by a CM for the first week of October, with the rest of the month reverting back to the "regular" schedule.
We arrive October 14 (first day in the parks will be Oct. 15) so I am planning on the regular EMH being in effect. The changes they made for the summer months were supposed to be temporary. Obviously Disney will eventually post them but they will probably keep changing them after they put them up!
Even WITH the hours I wasn't able to move my FDP for Hollywood & Vine. That 4:30 slot is still the best they have for now. I'll be calling back in September to see what opens up.
Happy planning, everyone!
