Of coure the Society has made correct predictions. Lots of 'em. Here are a few. (Notice the publication dates)
1) (W09 9/1 p. 30)
"...the Bible promises that soon the earth will be a physical paradise."
2) (W83 3/1 p8)
"The difficult time all faithful Christians are now having is soon to end, for we are rapidly approaching a new, happy era. We are on the threshold of "a new heaven and a new earth."
3) (W52 12/1 p709)
"...now, by occurrence of every detail of the great sign Jesus gave, we know that we face the imminent end of the present world system."
4) (W50 3/1 p67 par1)
"The rapidly approaching battle of Armageddon makes the matter of praising God increasingly urgent for survival."
5) (W50 9/1 p286 par14)
"Shortly, at a thief-like hour, the Supreme Warrior for truth and righteousness will make himself known to all his opposers in a language that they will understand, the language of cosmic forces that will speak destruction to them."
Of course, this all depends on how you define soon, threshold, imminent, rapidly, and shortly!
