1) I’ve heard it quoted from the תלמידים of the גר״א that כלל ישראל in ארץ ישראל is משיח בן יוסף and לאו דווקא will משיח בן יוסף die if they live past 5771 which is the ראשי תאבות of the פסוק in אז ישיר “אמר אויב ארדוף …״ until אריק so that makes sense with what geulah time was saying
2) Amnon Yitzchak has said that the world will go crazy until the year 2030 (you can find out his predictions on YouTube) and he said some interesting things that will happened beforehand
