We've got more 2.3 info for you, thanks to the fine folks braving the Public Test Realms. Szilia, a frequenter of World of Raids has compiled a great post on the Dustwallow Marsh changes coming in 2.3. Head over to take a look.
On top of all that, there are also a few posts from the Blizzard Community team that deserve attention.
LFG System Improvements

We have some improvements on tap, that we'd like to implement at some point in the not too distant future, if time permits of course. We're not quite ready to discuss them, unfortunately. In any case, we realize that the tool needs further design work before it's completely effective.
Death Knight models and art still not finalized
Bornakk wrote:
The art and models that you have seen for Death Knights are likely not finalized as we have a ways to go before launching Wrath of the Lich King so they can definitely change.
All weapon skill bonuses changed to 1% crit
It is converted to 1% critical strike.

I believe all of the racial weapon skill bonuses were changed like this.
Will Season 1 & 2 gloves get Season 3 bonuses?
Eyonix wrote:
We have no plans to do this anytime soon, or even moderately later. I'd purchase the season 2 gloves and sleep easy.
Headless Horseman difficulty?
Bornakk wrote:
Be ready to get your group together and ... be prepared!
The rest of the instance isn't changed to be for level 70s though, just the Horseman himself.

Finally, there are two new screenshots up on the Wrath of the Lich King site. There hasn't been a news post about them on the official site yet, but my amazing detective work (AKA clicking on the Screenshots link) has uncovered the treasures of the North.

On a personal note, I'm pretty happy. I was finally able to get my characters copied over to the PTR (the copy process didn't even work for me until around 12AM PST last night), so I'll get to report on the leveling changes with my priest!
