Yes, for God's sake keep the ring motors out of the Limited primes. IIRC the DA Limited HD vs SMC review on this site somewhere let on that the biggest winner for the HD treatment was the 40 pancake, which was also the oldest of the Limited lenses (and heavily based on an M-series lens). This makes me suspect that the only thing the FA limiteds really need is an update to HD coatings, possibly quickshift if that isn't too difficult (and looking at the 40 Pancake I can't see it adding much if any volume), and nothing more.
