When 800Z was threatened with extinction last year I emailed Fuji UK to ask if this was global or not. The reply was that this was global, but of course Fuji later changed their minds. Any how, the email I got also said that Fuji UK would not risk ordering anymore of this film as they were worried it wouldn't sell:

My last order date for stock from Japan is mid Sept 2009 and
this stock would normally be due to arrive in the UK in Jan 2010. However,
I have no intention of ordering any more and taking the risk of it not
being purchased by UK wholesalers/dealers. We still have some stock left in
the UK and we will just run this out
Now, I wonder if they decided to risk ordering the 135 films but thought 120 was still too much of a risk.
