Well it's not so long ago that Kodak revamped some of their films and Foma have recently had to make changes to Fomapan 200. Fotoimpex in Germany have been working on new versions of APX400 and 100.

Ilford have introduced new papers and it wouldn't suprise me if at some stage there was a new film. So yes there is R&D still going on, obviously at a slower pace than in the past.
