As mentioned above, it was announed mid 2013. A wonderful film I've been buying up as I could. It's expensive stuff so I just get a few rolls at a time for the freezer. I like to shoot it in 35mm for projection. Great slides, great film for shade or overcast days. I prefer the color and contrast for most scenes to Provia 100 as it's not quite as contrasty or saturated and looks more real to me with less tendency to blow out highlights. In that sense it was almost my replacement for E100G, which had been my replacement for Astia, with the benefit of two stops more speed albeit the cost of more (but not bad for a 400 slide film) grain. Sigh.
I'm not sure how well a slide film this fast will keep even frozen, though. I'd think at least a couple of years past date, probably more. I can probably afford to buy up all I'll want to use this year and next. After that - well it's either give up slides in all but good light, push 100 two stops, get some of that 200 from Germany and push it, or maybe shoot B&W slides for dr5.
