Via their podcast The Kodakery, Kodak have offered an update and some in-depth discussion about the efforts to bring color slide film Ektachrome back to market. While they don't give a hard date that the film will be available at retail, they do project that it will come to market in 2018.
"In January of 2017, we announced that KODAK EKTACHROME Film would be coming back to the market. The process is coming along well. We’ve been busy testing and making sure it meets all the expectations that exist in this passionate community and are looking forward to its market release in 2018."
