This week I bought 10 rolls of 35mm 800Z from 7DS and they came without boxes. I emailed them to ask when the expiry dates were but, as usual, they didn't reply. So I wrote to Fuji UK and I also tacked onto the end of the query a question about 800Z's future. Is it actually discontinued, I asked. This is the reply:

Pro800Z is now discontinued, there will be no further manufacture, we still
have some stock left in the UK, but when this is gone it will not be
replaced.
