Future expansions.

I'm playing WoW, and all this "steampunk" stuff is annoying. Warcraft isn't steampunk, so why are they adding this nonsense?

If it's not too much trouble, could you briefly explain why Forge was canceled (or provide a link to more details about this story)?

The developers initially wanted to include the Forge faction, a Castle of sorts for all kinds of bio-technological weirdos (like naga tanks, goblins with guns, and zombies with chainsaws for hands, and other wonders). This was related to the endings of Might & Magic 7. They planned to make the "evil" ending canonical, in which a piece of the ship was used to launch the Sky Forge, producing pew-pew rayguns and other things to establish world domination. But then they chose the "good" ending, in which that same piece launches the Stargates. When Forge was announced and the concepts were demonstrated, the devout Heroes of Might and Magic fans on the entire planet united in a common effort and bombarded the idea with criticism on all possible forums and declared it heresy. The developers quickly put together a hodgepodge, not caring about balance or anything like that. That's the story.
