It follows the standard curve that a "mature" console's software sales usually do: the low end of the spectrum has fewer first-party titles, then it peaks around the million mark, curves back down through the lower millions, and spikes back up as you approach the top sellers for that system.
Sky Render - Sanity is for the weak.
