My guess is that the Link bracelet is too pricey for many and wasn’t the success that Apple hoped, hence they have debuted Graphite with a matching Milanese. Hopefully a matched link will come once more have been sold through and there is a bigger potential market.
I must admit I really liked the Milanese, too, and it was primarily the scratch-risk that put me off using it on a regular basis. With the Graphite Milanese being PVD that risk should be minimised so I will be happy to run with it as a daily band.
But I still love the Link, and hold out hope for it to become an option.
