Plum Fumé is still there, the Fumé models are listed separately (lower down the page). I don't think they're planning to do those in the new sizes - not yet anyway.
I made the same mistake and panicked briefly when I couldn't see it the medium plum is still my favourite. I was a bit late to the party on this one so probably back of the queue 😴

New AnOrdain Model 1 sizing is up on their website... 35 / 38 / 41. The 41 sounds like a whopper, with a 49.5mm lug to lug.
