As Herb did not offer them the past months I have contacted him via his private email.
His reply:

Hello Erich,
Here is the situation with the cupholder. We made the mold and ran
the initial quantity of parts. I sold the last of the parts about a month ago and the only way to sell more is if I have another molder make them for me. My cost for a limited number of parts is a bit over $1200. That means I'm out of pocket until I sell about 40 cupholders. If we can do that I'll have the parts made.

The cupholder price has been $29.95USD for the past several years, and seems to be reasonably well accepted. Shipping/handling has been $8.50 for US and Canada. To Europe and your area (Asia)the shipping cost is higher, but not a huge differential. As far as RHD is concerned, I think I should refrain from that option. Herb
-----------------
Additional info from my side: that cupholder does not fit on consoles which have the holder for ASC and/or EDC.
Fits on E34 and E32.
It fits, however, on center consoles for automatic transmissions and for manual gears/shifters.
Here are the pics how they look. Please post if any interest, then I will inform Herb and he has to decide to go ahead or not. I will link this post also on other boards. If he goes ahead, you can buy them on Ebay.
