Latest Posts on the Whole "Mashiah in Av 5772" Concept
The Absolute Truth wrote that he verified the whole concept with the wife of Rav Zaccai - the Havruta of Rav Kaduri ZTVK"L.
On the other hand, Geulah Perspectives has a podcast that says:
1) (31:30) We cannot guess that Mashiah will come in Av 5772
2) (36:15) If we say Mashiah will come in Av 5772, we can be assured that he will not come at that time.
Time will tell.
