I think that is the case. They have Acros II which they still produce (I think), and here in Germany we weirdly have Pro400H in 120 left on sale, but I think that is running out. Fuji 200 is Kodak Gold, Superia 400 is discontinued, the new Fuji 400 is likely Ultramax, and so on. The slide films are chronically unavailable and prohibitively expensive. I think they made the decision to kill off film production before the resurgence in recent years. Business decisions at that scale are planned years in advance. Also, the supply chain is drying up for certain chemicals.
All in all I think the FujiFILM name is not warranted any more.
