I think it´s pretty obvious why SOny is ahead at the moment. Wii Music and Animal Crossing haven´t had the legs Nintendo expected them to have and with RE5 and Wii hw constantly dropping it was obvious. April will probably be the other way round again with MH1+3.
edit: In addition, with stronger support from 3rd parties (EA, Activision), titles like Tales of next and DQ10 I can´t imagine Wii sales will decline in the long run. So far, the Wii has sold because of games such as Wii Fit, Play and Sports. What is going to happen with all those 3rd party games?
