I would love to see Nintendo experiment with it and put it in the next Zelda, even with Link talking. Of course it is "we/I" controlling Link, but we can't REALLY be him even if he has our name and all that. It's not necessary to to have the main character 1-Dimensional so we "project" ourselves onto him. We always can find a way to relate to someone who actually has a few facets to their personality, and that works better than seeing a voiceless character on screen.
