Agfa still offers film and chemistries. Agfachrome RSX II 200 emulsion on thin PET base. Maco does types 135/120 "Rollei" conversions.
The Fuji Provia rebranded as "AgfaPhoto Precisa" is by AgfaPhoto.
Concerning chemistries I would worry much less, as there are still some independant chemistries manufacturers around to offer alternatives to Fuji and Agfa chemistries if necessary.
