A reader of this blog was at Rav Elya's levaya, and shared with me that Rav Shmuel Kamenetsky, the Rosh Yeshiva of the Philadelphia, in his eulogy of Rav Svei, said that Rav Svei had said ten years ago that Moshiach would come in 2009.
A comment on the previous post gave the following link to a video of Rav Elya himself quoting Reb Elchonon Wasserman's statement in 1939 at 36 minutes and 20 seconds.
Another comment from 'גילוי' (keitz meguleh) stated that the seventy years spoken of are not consecutive, and in fact some of that time occurred before 5699 and some will occur after 5769 as well.
Another point worthy of mention was something my wife read in the Mishpacha magazine, which quoted Rav Kaduri (who the author of the article personally heard it from) as saying that on the day of Birkas Hachama (this Wednesday) there will be a sign of מתיקות הדינים - sweetening of judgments.
I found this last point to be very significant, as my הרגש tells me (for what it's worth) that we are in for some hefty רחמים from Hashem, and if we are indeed standing at the threshold of Moshiach, then the incredible miracles that await us will require the type of actions that are above the logic dictating what we deserve, getting us into the realm of Kesser.
