If you have to actually swing the damn controller every single time your arm is going to be silly putty after an hour.
I sure hope Nintendo gets game testers for this game. Can you imagine the lawsuits if they don't? Better invest in some acetaminophen too.
Seriously, this "arm-waving" argument is so 3 years ago. I *might* agree with you if this was a no-name 3rd party, but this is Nintendo. They aren't going to half-ass Zelda, and they aren't going to overlook a possible issue, such as this.
And about what "Miyamoto should focus on"... You're taking one comment about one aspect of the gameplay and making broad generalizations about the whole game. It's still early for them to be talking about the adventure aspects. I'm sure their thinking up new ideas and concepts, but if they can't go into details yet, there's no point for them to comment.
BTW, I do respect many of your arguments but sometimes, like now, you take an inch and run a mile.
