Is there any truth to all the talk over the last year about Fuji discontinuing their 4-layer print films and replacing them with 3-layer versions?

B&H lists on many of the Superia films as backordered, discontinued, and out of stock:

Maybe this is the reason...?

Why would Fuji revert to older technology, even with price pressure? Are the proposed 3-layer replacements for Superia supposed to be better than or at least equal to the current 4-layer films? Or is there a compromise? They made a big deal about the 4 layers when they introduced the Superia line.

Are we reaching the end of the era of readily-available high-quality, low-priced C-41 film? Or is my 'information' just wrong?
