I predict a new DS design this year or early next year

[FishyJoe]

I believe that Nintendo will release a new DS design at the end of this year or early next year. The GBA had new models every two years, 2001, 2003, 2005.

Also, the Wii will be two years old, meaning that no new Nintendo hardware will be released for over two years. You can't tell me they haven't been working on something all this time. 

I give a small chance that a mobile phone device will be announced within the next year.
