I think the trick is that as gamers, we need to let go of our preconceived notions of what a first-person perspective means in terms of game mechanics. The perspective should NEVER dictate the game mechanics, but more often than not, developers cater to the gamer and compromise the design of the game in order to meet gamer expectations. I was even told in no uncertain terms by at least one game designer that he considered Metroid Prime a "failure" because the controls didn't meet with gamer expectations. I personally think that it's the exact opposite. We're never going to be able to innovate in game design if we can't get gamers to open their minds and learn to adapt.
As for the interview, I've known Jeff for quite some time now, and he's a great guy ... he definitely knows his stuff. And while he might not have been more open about the questions asked (and unasked), I'm positive that he's aware of the issues. Jeff is very loyal to Nintendo, but he's definitely a gamer, and I have no doubt that he'll do everything he can to help make the game a success.
