Expansion speculation

So, since I seem to be on a roll today...

I'm very interested in all of the expansion speculation. I like the idea of two new species and (I hope) a new hero class, as well as an underwater, naga-land landscape (the Maelstorm). I would totally reroll as a Worgen, if that ends up being one of the new species, and I bet my wife would too. The biggest doubt in my mind that Goblins and Worgen will be the new expansion's species is lore considerations: it seems like even more of a shoehorn job than blood elves and the Horde was.

In my opinion, although Lich King brought a huge number of improvements to gameplay, lore, and questing, the endgame content has been something of a bust. Say what you will of brutal, back-breaking encounters in TBC, but they sure gave guilds bragging rights after beating them. Although I never had a chance to see them, you still hear people talking about Kael'thas, Vashj, and Illidan, and even some of the minor bosses, in a kind of awe-inspired tone. Hell, even Magtheridon, Nightbane, and Gruul get some mentions. Naxx was really a poor way to open up raid content, and definitely spoiled veterans and newbies alike, in a very bad way. Nobody cares or is impressed by Gothik (who used to be a guild-breaker), Razuvious, Four Horsemen, or even Kel'thuzad.

Ulduar was neat in concept, but it's getting phased out too quickly. Now the cutting-edge raid will be gladitorial-style combat? Seriously? Where's the epic-ness in that? I mean, the only big lore connection I have heard of is Anub'arak's return as an actual boss, instead of the panty-waisted excuse for a schoolgirl his 5-man incarnation is.

I really hope Blizzard comes out with the new expansion inside of a year. We need to move out of Northrend. I, for one, am sick of it already.
