Some good news of sorts, I emailed Lucky and asked them if they are going cease production of the SHD black and white line of film and got this reply:

B/W SHD 135 FILM 还有生产。

COLOR FILM 停产,尚有少量库存。

Which Google translate says is:
B / W SHD 135 FILM production there.

COLOR FILM discontinued, there are a small amount of inventory.

Rattymouse (or anyone who reads Chinese), can you verify that what Google says means B/W will continue?
