Wayne is in post-production on Shania's new video which should be out in the next few weeks, it was shot March 30. So, since it looks like it takes at least a month between shooting and release that's how I basing my guess. Of course Faith's video isn't even to the shooting stage yet, it was just booked April 20, so it might be longer.

If you'd like to check it out here's the links I found.
