This post starts with me saying this is an exaggerated speculation. As the man in question is so famous for these days -- Please understand.
But here we are in a week where two separate Directs have been released from Nintendo -- Smash Bros. and Tomodachi Life -- both of which were hosted by a member of Nintendo not named Saturo Iwata. Granted, we can chalk the Smash Bros. Direct up to the fact that Sakuri is the lead developer of the series, so naturally a 40 minute presentation specifically focused on his game would be led by him.
But this hasn't been the case before. Game showcases in Nintendo Directs have mostly had Iwata at the helm, with other Nintendo figures taking on a supporting role.
Then, we get to Tomodachi Life -- a game that I believe is exclusive to Japan -- and the man in front of the camera is American Bill Trenen (sp, I'm sure). Iwata's Mii showed up several times throughout the presentation, but the fact remains is we've heard very little from Mr. Iwata since the last full-fledged Nintendo Direct.
Is this fact telling of Nintendo's future? Has Iwata already been let go, and they're keeping it a secret so not to cause stocks to fall from nervous investors? Are they slowly shifting him out of his top position and trying out new faces? Or is this a whole lot of nothing, as is typically the case with all speculative discussions?
