Kimishima takes the reigns in a difficult period -- the Wii U is struggling, the 3DS is nearing the end of its lifecycle and Nintendo is about to dive into mobile gaming for the first time. In addition, the company is working on its new "NX" console and a mysterious "quality of life" initiative. Sure, the latter two projects were born under Iwata's watch, but it's Kimishima that will be taking responsibility for their success (or lack thereof). Meanwhile, Miyamato and Genyo Takeda, one of the lead visionaries for the Wii, have been given new roles as "Creative Fellow" and "Technology Fellow" respectively. Both will help Kimishima during the transition -- but even with their assistance, he has unquestionably huge shoes to fill.
