Nzoomed the vast majority of Super8 users already uses negative film, so as sad as this decision makes me it's a logical one no costumers no product it's that easy. The private Homemovie users are just too small a market to sustain the production of Ektachrome 100D. As AgX stated there are several suppliers of respooled Super 8 color reversal stock. Besides telecine isn't really that expensive anymore and you can do a lot more with the telecined stuff than the positive.
