YC Chrono lug-to-lug? New, even smaller YC Chrono next year?

Does anyone know the lug-to-lug distance of the smaller, 43.5 mm Port Yacht Club Chrono? I think it has to be about 50 mm or so.
Any info about an even smaller YC Chrono in the pipeline? I think a very same case shape/size like that of the 3714/3716 would be nice, so dropping the crown protector shoulders but maintaining the cal. 89xxx inside, the lume dial/hands and the 60 m WR....
Best,
Robert
