Are you thinking about sail shape, materials, or both?

I don't see any reason that the manufacturer couldn't "update" the sail plan themselves. They did with the auto-tacking jib, for instance. I think the same was done with the spinnaker, too. Nothing dramatic, but a little flatter shape with different shoulder. The new 3-point snuffer spins are even flatter I think.

It would take about 3 years for all the "original style" sails to exit the racing scene. I guess it wouldn't matter for the non-racing owners.

I can see the manufacturer's point that there is no "perfect" sailplan for a boat that accommodates crew weights of 325-400+ lb and various wind/sea conditions. It would seem easier (and cheaper) to develop a standard sailplan that is highly tuneable (through downhaul, prebend, outhaul, sheet tension, etc.)
