AFAIK, Reala is not "supposedly discontinued." These rumors start every year or so, though. The way I had it explained to me by Freestyle is that Reala is coated and shipped out all over the world only once every so often. When these stocks run out, the discontinuation rumors begin. Then the next run is made, and Reala returns to overseas (meaning not in Japan) retailers' shelves. There have been at lease three discontinuation rumors for Reala in the past five years, and none of them have proved true except for in certain formats in certain markets (England e.g.).
Nonetheless, I stock up on Reala in 120 whenever I can afford it.
