The first few posts here are posts that originally appeared on Dreaming of Moshiach.
In the Haggada, there's a song at the very end, and I dont know who wrote it, but it seems he may have known something.
קרב יום אשר הוא לא יום ולא לילה
the gematria of the bold is תשס"ח
recently, I was looking at the pesukim in zechariah perek 12 passuk 3. There it says:
והיה ביום ההוא אשים את ירושלים אבן מעמסה לכל העמים וכו...
the gematria of the bold words is תשס"ט and the end of the three words is אמת (I just noticed that now).
I recently heard from a very reliable source that Rav Elya Svei, Rosh Yeshiva in America said that in תרצ"ט, 1939, Rav Elchanan Wasserman said that Moshiach would come in 70 years. After I heard that story, I "happened" upon another story that Rav Elya Lopian said over from Rav Elchanan Wasserman that he was with the Chofetz Chaim in the beginning of World War I (circa 1914) and the Chofetz Chaim said that WWI was the first of three Gog Umagog wars. The next would be in 25 years. That story ends there, but clearly Rav Elchanan Wasserman was someone in the know.
Another interesting point is as follows:
the gemara in Rosh Hashana lists off the ten exiles of the Sanhedrin which correspond to the ten exiles of the Shechina.
it went from Lischat hagazit to a chanut, to Yerushalayim, to Yavneh, to Usha, back to Yavneh, back to Usha, to Shfar'am, to bet She'arim, to Tzipori, and ended in Teveriah. The Gemara ends off with a statement of R' Yochanan.
ומשם עתידין ליגאל שנאמר, התנערי מעפר קומי שבי ירושלים
from there (Teveria) will they be redeemed in the future.
