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?
