This that was linked from that blog says the same as all the rest.
RVP50 is NOT discontinued from the factory. It IS still being made in 135, 120, 4x5 (220 and 8x10 are gone I think). And it IS getting more expensive.
USA, Australia, and I think UK and EU reps have all confirmed that it is discontinued for SALE there, but it IS still being MADE in the factory and IS still available in Japan.
So all you can do is buy from fleabay or a Japanese distributor. The more you buy the more they might be inclined to continue making it.
Fujifilm have NOT announced any discontinuation as far ahead as 2017 or 2018 (if anyone says otherwise, please send me a link, preferably to a fujifilm site or press-release).
Anything saying so are just unfortunate rumours.
(and yes, Go Ferrania! They'll be all that's left in E6 if/when Fujifilm pulls the plug completely).
