Yes, but if they ever introduce autoplaying ads (extremely likely), I'd imagine that users with slow connections (most of us) would take a serious hit. To quote Brandon from below:

"Right now we don't have pre-roll ads on the test videos, since we're focusing on what kind of content resonates with users and what the best placement is for videos. But we'll probably be doing tests that have pre-roll on them too."

Autoplaying ads means that more users will see them, which means significantly more ad revenue for Wikia. I'm sure they're interested in autoplaying videos. Even without the sound, it would be obnoxious.
