Sorry, I forgot to check my logbook of official Brawl info to see that the 40 characters thing never came from Sakurai. Whatever. The point is that a developer can "go on record" about anything. More often than not, they're just answering questions in interviews and end up contradicting themselves, albeit not on purpose. It's not that I don't trust Sakurai. I prefer to trust the development process which has its share of ups and downs. Sometimes it's rushed, sometimes the hardware isn't adequate to implement certain features, sometimes it's decided that certain features absolutely have to make it in even if it means a delay. It's not about habits, because it's not a habit to run into problems or forks in the road during development. I doubt Silicon Knights planned for Eternal Darkness to be moved to GCN or Retro having their asses handed to them by Miyamoto and told to change the entire direction of Metroid Prime or Blizzard realizing that Starcaft: Ghost just wasn't good enough to be released after 34681976 years in development under just as many teams. Basically, sh-t happens so I choose to take everything a developer says with a grain of salt. Sometimes they're lying through their teeth, other times something unexpected happens.
And last time I checked, Iwata is the president of NCL. It's his job, among many other things, to know the status every 1st and 2nd party game in development or planned to go into development. I also find it hard to believe that Nintendo wouldn't make another Smash without Sakurai. They'd probably prefer not to, but this is the same Nintendo that allowed Capcom to develop a Zelda title and let them include a kangaroo with boxing gloves that Link rides in. At some point (maybe not anytime soon), Smash will be in someone elses hands.
