君はメロディー♫

yes, I'm a bit sad too because DREAM is my best, but after many heart broken news such as Love disband and Erie left, I always prepare for sth happened >.< My worst nightmare is EXILE and 3JSB (and my new sons The Rampage) got bad new so I understand you.
About sandaime, Hiro once said he want to revive JSB, that's why he created nidaime, but they were merged with EXILE too quick. But Hiro is stubborn one (too stubborn some times), and we have our treasure 3jsb now, as in the time 3jsb was created, Naoto and Naoki seem the ones close to the age with new members was recruit and Naoki is also Gun's senpai. Actually NaoNao knew they will become co-leader for new group bf VBA2, some rumors said because Hiro has the humour in him that why he chose those two like the shortest one and the tallest one :D as long as sandaime still go strong I don't think Hiro need yondaime as his wish is fulfill now ^^
