Is 220 Velvia still currently manufactured and not discontinued and running off stock?
I grabbed a single pack of 160NS 220, which is the last C41 220 available. Discontinued but still stocked around Asia.
There is a rumour about Shanghai GP3, which was discontinued due to a factory upgrade or whatever, becoming available again in rollfilm format. There's Shanghai Pan in Sheets, so it's a sign they went forward. The interesting part is that there was consideration of making 220 if the 120 was rather succesful (5000 roll run).
The most recent is by Stearman Press, about a month or so ago posting in LFF (IIRC). So far not much known about it though.
