Here's a brief rundown since my memory isn't the best right now, if any details are wrong, pleas point them out. I'm not exactly sure of the names either, apologies in advance. There will be a video of the entire thing posted in the future.
1) Mr. Lum comes on stage, talks about a history of rides and the future. References Big Bad Wolf.
2) Guy in charge of Howl-o-Scream comes on stage to talk up the 13th year. He first introduces "The Lady of the Garden" (the zombie woman you see in the advertisements), and she comes on stage with hooded figures. Once he's done introducing her, there's a rather impressive little show where characters from all the houses, scare zones, and shows come on stage and introduces each of them one by one. I'll post my notes about them below. Once he's done going through what's already been announced, he announces Fiends and they come up on stage.
3) Once they're done with HoS, Lum comes back on stage and starts talking Verbolten. Pretty much everything we've seen before, I'll post notes below and in the Verbolten thread. Once he's done talking the story, the name is revealed. It's revealed by the center platform being lowered slowly, with lots of fog, and various engine revving sounds. With all the smoke and sounds combined with the slow lowering, it gave the impression of something being wrong with the car.
4) After that they have the raffle, and a Q&A session.
Notes
1) I think the Lady in the Garden is a great thing, I really hope to see her in a significant way during HoS.
2) The HoS introduction was the highlight of whole thing, check out the video once it's up.
3) It was really stressed that HoS is going to be scarier than previous years, a stern warning was issued to parents that it's not right for kids.
4) The nurses in the Fiends reveal......wow. I believe that the Animaniacs said it best with, "Hellllllllllllo Nurse!". Mini-skirts, garters, and the most cleavage I've seen in a BG costume. They're really pushing the limits.
5) On a similar note, they're going a bit farther with the gore this year as well. Think Hellraiser style for Stitch in Time.
6) The few things we were able to find out about Verbolten in the way of stats were that it will have two launches at 50 mph, it will be taller than the BBW drop but I don't have the exact number, and that it will have the same S-turn.
7) I asked if Mach Tower will have normal operation during Christmas Town, Mr. Lum said that they're looking at normal during the day and an observation mode at night.
8) While they were speaking, he mentioned Europe in the Air as one of the quality rides, which promptly caused our group to giggle, which promptly cause a quick glare at us from Mr. Lum. We also giggled when they made a point of Verbolten opening up on time.
9) Catacombs will be double it's size this year.
Any other questions I can try to answer, but you might want to just wait for the video.
