It's simply getting adjusted to where it should be.
Nintendo has been the market leader (by a large margin) in both game platform markets for a while now.
At present, it is not certain if Nintendo can continue to lead the market, and it seems inevitable that the WiiU will sell less than the Wii, and that the 3DS will sell less than the DS.
Also take into account that Sony seems to have more of a stronghold in the BRIC countries.
