Nintendo has been investing in some mobile company(ies)...... Not exactly sure what their purpose or strategy is. IMO they should release some Nintendo themed games that go well with mobile- more designed to create/maintain awareness and even draw traffic to their Web site. Do something like Rayman Challenges, but on your phone/tablet with Mario, Donkey Kong, etc.
People say that mobile gaming is a big threat to the industry, but when I got my iPhone I did play it for a few days, I played it constantly. Then I realised how I could be playing much better games on my consoles. And I stopped playing mobile games. People that think mobile gaming is equivalent or better than console gaming obviously haven't played console games before..
