Not sure if this was discussed or not, but...

For those of you who hate tiles, rejoice! Despite my love of cardboard jigsaw maps, it looks as if WotC are releasing affordable ($9.56 on Amazon) maps.
This accessory includes three double-sided 21" x 30" tactical battle maps -- a total of six beautifully rendered encounter locations, each one suitable for any D&D game. Each map is laid out on a one-inch-scale square grid, allowing it to be used with D&D miniatures and/or card stock tokens.

Two of the mapped locations are new, depicting a dark cathedral and a haunted chapel with an adjoining cemetery. The remaining four map locations are picked up from out-of-print D&D products and present adventure locations tied to the "haunted temples" theme.
Release date is January 17, 2012.

And if it wasn't confirmed, Elemental Hero's Handbook:
Masters of fire and earth. Lords of air and water. This tome is the definitive sourcebook for creating and playing characters with ties to the Elemental Chaos and the primordial beings that dwell there. It shows how the elements can influence heroes of the natural world and presents elemental-themed character options for players.

In addition to discussing elemental power and presenting new character themes with strong story hooks, this book includes three new class builds--the elementalist, the sha'ir, and the shugenja--and new feats and paragon paths designed to tie existing characters more closely to the Elemental Chaos.

So three new class builds and a ton of options for incorporating Elemental into existing characters, as many suspected, and again partially leaked from Comicspalooza.
