I've added a YTD sales column (total 2012 sales). Also, "Weeks Left" column has been divided so that it calculates the number of weeks left based on current weekly sales, the average weekly sales for the last 5 weeks of sales, and the average YTD weekly sales for the whole of 2012.
Oh, and congrats to 3DS for passing 20m!!!
An interesting find is that based on the average sales for Vita during 2012, it's actually AHEAD of 3DS. It really shows how its sales have fallen after its western launch...
