Good question! In short: we don't know yet. :)

Because of how wiki content creation works, adding videos to pages is very similar to editing a wiki -- you're never actually "done", there's always something more to add.

It's not possible for our Video Team to put video on all pages on all wikis (and some pages may not even need a video), so we need to prioritize.

You're intuition is correct: we're going to start with the highest-trafficked wikis. More specifically: we're starting with the highest-trafficked pages. We don't yet know how far down we want to go -- where the stopping point is. That's hard to determine because the list of top 100 wikis changes as new games, movies and TV shows are released.
