So then their use of the term "expectation" is actually a big lie, because it was not merely an expectation, it was a PREDICTION. They generally did not say "we expect this to happen" (except maybe with the 1925 stuff, "we may reasonably expect..."), they said "it will happen". Even going so far as to say that God would make sure that it happened! (May 15th, 1984 WT p. 6-7)
It's just a word game they like to play, and unfortunately too many are being fooled by it.
