he was legend. no more iwata asks and directs 
Directs will probably continue, but if you ask me
Iwata Asks was his real legacy. So much insight into the development process for so many old and new games. In terms of knowledge gleaned from the development process, the sum total of Iwata Asks probably outpaces EGM, IGN, and any number of enthusiast press sites and magazines.
I'm not sure whether I want them to end, or whether I want them to continue without him. I can't imagine any other CEO interviewing devs like that and being able to interact on such a technical level with interviewees.
