$10 for a year's subscription to the 3.x Eberron catalogue. That reveal was by James Wyatt (I think) and was not supposed to have happened.
I was there this morning. Here's a summary to supplement what was above.
Dungeon of Dread - Cancelled
Lords of Waterdeep boardgame in March. Euro-style board game making extensive use of Volo's Guide to Waterdeep.
Madness at Gardmore Abbey - $39.95 box set with maps, monster tokens, more open-ended than linear in style with various patrons/enemies. Cards from the included Deck of Many Things are scattered around the abbey and grounds and are the objects the PCs are tasked with finding. The cards influence the encounters based on which cards are where.
Mordenkainen's Magnificent Emporium - Uses the rarity system. Character options for weapons specifically mentioning flails I believe. Also includes mundane items, followers etc. Mearls said rituals aren't in the book (My question!) Regarding rituals, he want's them to be useful at all tiers and mentioned scaling effects that you can pay for and such when they're reintroduced.
Box set of limited edition chromatic dragons like the Beholder set.
Heroes of the Feywild - Ties into the Encounters season based on Beyond the Crystal Cave. Pixies which can fly from Level 1. Will mostly be Arcane power source with Primal mixed in. As mentioned the Barbarian is a Defender who becomes a Striker when enraged. The other two races are the dryad and satyr. New Bard and new Druid builds.
Two new Dungeon Tiles sets - A haunted house and a "Gygaxian" crazy dungeon
Map packs like Dungeon Tiles - 3 maps for $12
Book of Vile Darkness - How to run evil campaigns. Includes a 32-page (I think) Book of Vile Darkness
Power of the Plane Below - Elemental power source. An Essentials Sorceror. E-Sorceror will focus on one element instead of all four. Also an elemental Monk. Oh, and a Shi'ar build. Al Qadim was mentioned and generated some enthusiasm if they explore it through DDI.
Undermountain - I zoned out a bit. Sorry. It's a map of the tavern and the first level of the dungeon. I think it's a dungeon generator product.
They do have a new campaign setting they aren't ready to announce. Supposed to introduce a twist on traditional play. Not useful, but I understand not announcing until you're ready.
If possible, monster tokens will be included with new products. Response to tokens seems good.
New Runepriest build coming... somewhere. DDI I think?
They want to take their time and use care with less popular classes and races to address issues as to why they think they aren't as popular. Vampire from Heroes of Shadow is hugely popular immediately shooting into the top eight created classes on the Character Builder. They don't want to "Essentialize" classes that aren't as supported as they want to give support in a broader sense.
Products tied to Encounter seasons will less likely be box sets as that hurts portability. Items not tied to Encounters will more likely be boxes.
They want to introduce and explore settings in DDI and if they prove popular move them into print.
Exploring how to release their library digitally.
Looking into mass battles systems.
Want to better organize website.
New line of miniatures that are based around themes. Around 60 miniatures in a pack and will have a diceless, tactical skirmish game. It uses Dungeon Tiles. There will be an open playtest.
