The word I got on Reala was that it is made and ships only once a year from Japan. Therefore, people in other countries often think it is discontinued when the stock for that year sells out. I've thought that Reala was discontinued in the U.S.A. and brought back at least twice before being given this information by Freestyle.
It makes sense to me that it is going away in 135 format. I don't think that most people who shoot transparency films nowadays are doing it to have some slides to project. I think that most who bother with them are using larger formats and scanning.
