Absolutely awesome. Here's my quick translation notes.
Hardware and loading times
First they talk about loading times. 2-4 second loading in-game. But Aonuma said he had envisioned the necessity of a "loading in progress bar" first, but the loading was so quick in Zelda, it didn't become necessary. Also if you leave the game in the Wii, it will load it up quicker next time. Using the internal Flash. Iwata also said he hopes they will be able to make the "channel switching" even quicker in future updates. They are so transparent and honest that they are not happy with startup times yet. Iwata had a goal of 3 seconds from pushing the power on the remote to game start. "We didn't make it there yet unfortunately" he says honestly.
Zelda development
Before they decided to delay by a year. A lot of fantastic parts were done, but lacking unity. Miyamoto was very concerned about this. But it was Iwata who proposed to Aonuma to give it another year. (My reading between the lines give me the sense that Miyamoto hinted to Iwata that it was a tough situation).
Later Iwata end up discussing what "Zelda" is as a concept. Aonuma starts babbling a bit. But Miyamoto simply says, the Zelda concept and Mario concept actually are very much alike. Why? Answer follows in next segment.
I love these interviews.
