Kodak have just ditched several films with no advance warning and no replacements:
Portra 100UC and Portra 400UC have been discontinued in medium format, but are still available in 35mm. I never liked 100UC, but I really dug 400UC 120 in a Holga.
Ektachrome 160T (EPT) and Ektachrome 320T (EPJ) have been discontinued completely.
Awesome.
