Currently iwata is doing fine, however I feel if he doesn't provide Nintendo fans and potential Nintendo fans (those unsure or against Nintendo at the moment) with new and interesting IPs by 2015, I think it's better for him to step aside and hand pick a younger leader to replace him, one with fresh game ideas, who maybe goes against the grain of the usual Nintendo retric - breathing new life into Nintendo who seem to be making old games with new twists time after time (which I love myself but they aren't exactly attracting different hardcore* audiences). When maybe it's time to try new audiences too along with keeping their strong and loyal fanbase happy.
I myself have faith in Iwata and believe he will be promoting younger developers and maybe even scouting talent from Western and Eastern third parties to bring us new and fresh titles by 2015, he is already bringing new IPs but currently none are what I call different enough to attract a non-Nintendo audience.
*What I mean by hardcore is any game that isn't Wii Fit U, Party games or Wii Sports, so yes that includes Mario etc unlike some people who choose to have ultra violent games as hardcore.
Do you feel Nintendo needs new leadership? Do you feel Iwata is doing everything right? Do you feel that Iwata should step down under certain conditions? Do you feel this topic is a waste of alphabet?
