I too have "heard" this - including here I believe. But take it as a neutral statement. And I don't think it is contrary to what you were told regarding "no present plans to discontinue processing".
My guess is that this is "speculative thinking" in the vein that, if and when Kodak finally discontinues making Kodachrome, then Dwayne's will likely cease processing it about three years later (i.e. after "clearing" the last fresh dated stuff from the marketplace).
But PE will likely know more about this.
