Nintendo has just announced it plans to introduce a successor to its Wii console next year, a "playable model" of which will be shown off at the E3 gaming expo in Los Angeles coming up on June 7th. No details are available as to how the next Wii will improve on the first one, though we imagine Nintendo will be happy if it simply matches the success of its current-gen home entertainer -- the brief note publicizing the new roadmap also comes with a total of Wii sales accumulated between its launch in '06 and the end of last month: 86.01 million. That's said to be on a "consolidated shipment basis," so maybe Nintendo is mixing its definitions of sales and shipments the way Sony likes to , but it's a mighty big number either way. Bring on E3, we say!Bloomberg has provided the first official hint about Nintendo's next console with a quote from company President Satoru Iwata. Nintendo will "propose a new approach to home video game consoles," though it won't be a simple move to 3D, as Iwata notes "it's difficult to make 3-D images a key feature, because 3-D televisions haven't obtained wide acceptance yet." Given that motion gaming is no longer new and 3D is off the table until 3DTVs go mainstream, we're now left facing only one potentiality -- Nintendo is planning on bringing genuine innovation to our living rooms. We suppose it also adds fuel to the rumor of a crazy next-gen controller to go with this next-gen console.
