Now FFXIII-2 is a million seller on PS3, I had a quick look on game DB and found out it was actually the 133th million seller on PS3, while Wii has only 131.
We are in a most curious situation : the best-selling system has the lowest amount of million sellers (and 500K sellers), but it's the only one to have 20 million sellers. What does it mean? High concentration on some titles, so an audience much less varied than the the HD competition. Also, PS3&360 million sellers have many more high quality titles than Wii's.
The question is the following : with so many people playing the same games, can Wii still be called the leader of the generation?
