RE: An end to tuning?
As you've said, we're already seeing bow designs that make it much easier to tune the bow properly. The average bow can be set-up and tuned fairly well within 20-30 minutes. Most of this time is spent setting centershot and nock height. To eliminate this, they would have to have unbelievable manufacturing tolerances for the bow and the strings. They would also have to eliminate spine variation on arrows and design a bow that can't be torqued. These things would be difficult to acheive and I don't see it happening anytime soon.
I wonder how they would address a situation where someone wanted to change the tiller or shoot fingers while hunting and mechanical release while target shooting. Things that require different settings for the rest and the nock height will require tuning.
To me, tuning the arrow is the harder part, and I don't see this part being eliminated by the manufacturing process (though they can improve on things like spine tolerance, and other manufacturing tolerances that will speed the arrow tuning process).
It would be a tough sell for a manufacturer to get me to buy such a set-up, but may be that beginners would be attracted to such things. I know that those who are just getting into archery tend to like things like crossbows, draw-locs, and other gizmos that make archery more simple.

Paul, I agree with the statements made by those well-known archers when it comes to target shooting. However, I think tuning is very, very important when dealing with broadhead tipped arrows being shot at animals, where maximum penetration is important, and you're not shooting in controlled conditions. Those guys were primarly target shooters and I believe their statements may have been made in reference to that.
