If you copy the Japanese text and past it into "altavista babel fish" you will get this:
" 2006 October 20th Fuji film corporation フジクローム Velvia (ISO50), there was also the circumstance of of procurement difficulty of the part raw material, did last production on end of the last year, ending sale with present stock, the effect which it receives it guided. But, you considered to the importance of duty, as this corporation that it receives the demand whose Velvia continuance is stronger than everyone of the photograph fan which your long time patronage it receives protects photograph culture and raises started advancing the examination of resumption of production from various angles. As a result, the possibility of the Velvia II (the tentative name) development production which has the efficiency which almost is equal to existence Velvia with the development of the part alternative raw material and the establishment of new production conversion technology, stood, could point to sale and became to receive.

Where they saying they can't get the "good stuff" they used to put in Velvia 50, but as everyone likes it and they think this important, they are going to make something nearly as good, to be available next year. This (original) stuff is probably still on the shelves in Japan as are many other films not seen outside Japan.
