According to a Sterne Agee analyst, we may see the first glimpse of Nintendo's next Wii platform at this year's E3. Support for Wii has been low at best, with sales declining and lack of developer support wavering further. In addition, the Wii has lost its unique motion control appeal with the introduction of Microsoft Kinect and the PlayStation Move to the motion control market.
"Microsoft and Sony are expected to persist with the current consoles for the foreseeable future (at least 2 to 3 years and maybe longer). However, Nintendo will likely need to introduce its next upgrade (Wii 2.0?) much before that, simply to catch up with the technology in the PS3 and the 360. Wii's motion-controller advantage no longer exists given the introduction of Microsoft Kinect and Sony's Move last year.
"We would not be surprised if Nintendo unveiled the specifications of its next console at E3 in June this year, followed by product introduction early next year."
