Graham, yes there is that drip-drip effect of the lighter material. delaying purchases and dropping prices Seeing in the bargains alert thread that Vasco now 99 quid shows the lighter jackets allowing the older jackets to drop in price.
Also, as Paramo Analogy tends to deliver its best use in the cooler months, its now February, and I found April the last Paramo month so if you'd buy now you'd not use as much and risk through the summer Paramo make more things (like the sleeves) in the lighter option, which you can then get a full winter season's benefit next winter.
Also, the lighter material has a stronger argument for what you pack more than what you wear. Paramo's Analogy "too warm" problem tends to mean they are worn in winter to replace mid+shell so are worn all day, and to a significant degree that nullifies advantages in weight. The items like the Torres range (inc sleeves) are a packed item and its not just weight but also volume. For many of my journeys I'm as sensitive to volume as weight. The Torres light gilet claimed more compressibility, hence smaller.
Of course the opposite problem is Paramo will charge more for the lighter products and bargains will arise for the older models, so at the same time you see the lighter ones you'll be torn by the $ saving of the heavier ones.
My personal view is that for a Quito owner or other jacket owners with essentially the capability of the arms to be exposed (3rd element, etc) is you can get lighter & cheaper under-jacket arm warmers which can do a similar, but certainly not as warm, job so I'm also not rushing to buy the Torres sleeves.
Surely the folks who need these sleeves know it already, they have cold hands that gloves aren't sufficient in particular situations.
