Reading the press release, they talk of AGFAphoto "Branded" film, and don't mention APX400. Maco has been only selling the APX100 stock. As someone else metioned, Ferania themselves have said they are no longer making film, but the US plant was always a packing/converting plant for private label products.
Ferania USA could probably convert, perf, and package any master roll of film, from almost any source. Hard to imagine that any actual AGFAphoto made colour film would still be arround, but perhaps some of Ferrania's 2008 production is still in stock.
AGFA-Grevert is only set up to make Polyester base film AFAIK, and the stuff sourced from there is mostly from their Military-Industrial range. Thus Maco's S series films.
OTOH is is hard to tell the players without a scorecard, and several smaller makers are now capable of coating stuff, and sending it out to be converted.
