Hey Blizzard fans! Artaxs here with some inside info on the new WoW expansion, Wrath of the Lich King!
So, I managed to strike up an off-the-record conversation with two of the community managers from WoW, and I had a chace to play some of the opening quests from the new Expansion on the Horde side.
First off, they confirmed that Northrend, the site of Arthas' castle, IceCrown, will not be an entirely iced-over continent. The opening zone I played was coastal, and the neighboring zone to the north is Sequoia / Redwood forest. They said that they were hoing to avoid what they called "The Kalimdor Mistake" ie. repetitive boring desert everywhere.
Secondly, yes, the level cap will be raised to 80. The new profession is "inscribing" and *yes* we will be able to use flying mounts in Northrend, but not until "level 75 or 78" as they want to "keep us grounded and guide us on foot" as we start exploring the new continent.
There weren't any new talents to show off in the demo, but I picked up some interesting drops including "Frostweave Cloth" -- at least we know that the tailors will be kept busy!
No one wanted to talk about release dates, but it's Blizzard; they will release it "when it's ready". =)
I got a chance to play the Terrans in SC2, but I don't think I'm ready to take on TwiceUzi yet.... maybe after a few more rounds and some time with the Protoss I can challenge our resident RTS expert to a match.

I'm also a little angry about the moving of Dalaran to Northrend... Yes, OK, myabe this will be the first thing in WoW that got changed and pushed the lore a bit forward but this step is controversial. How this could be miraculously rebuild when the Kirin Tor is in ruin due to the Forsaken's action on that terrain, and even (z0mg) moved like a space ship to the Northrend, over the seas :OO For me it sounds like a rubbish... I hope this will be explained somewhere in the future or maybe Kaplan will say a word about that on the upcoming chat
Cheers
