Microsoft is serious about Windows 8, and if you're serious about submitting Metro-style apps then there's now a healthily long and detailed blog post (at the source link) explaining how.

As the real person in the video after the break makes clear, your first goal should be to reserve your app's name so no one else can take it. (You do have a name for it, right?)
