Here is their reply:
Sorry for keeping you waiting for our answer so long! We have been discussing with the manufacturer about your question. They still cannot give any specific date but they want to inform that the smaller Lunette cup will be launched in to the market still during the spring time.
We will keep you up-dated once we have more information.
So I guess that is northern hemisphere spring (May, maybe?) so I'll just have to keep waiting. :( I'll let you know if I hear anything else, since I get their regular newsletter.
