I didn't see this posted yet and I just have to say that it is a great and interesting read. Im excited to read the rest of the interview as it gets put up because it gives great insight to two HUGE industry figures' lives, and goes on to explain their cooperation in creating a mega title.
It also is a good preview of what Sakurai will likely talk about in his presentation at the GDC... check it out:

I also like it because its a signal that Nintendo is really going to start turning up the hype machine for this one soon. When the president starts getting this pumped about his product, I definitely do too.
