Here's a couple to get you started (also don't forget idol EN gen 2 auditions closed just over a month ago as well).
And out of curiosity does anyone know if Aozora Kurumi, the Air Asia vtuber ever reincarnated anywhere? She was friends with Remi if I remember correctly.
Lumi said the next wave of Invaders were coming before Gen 3 and I've heard both Lumi and Tenma talk on stream about hanging out with them on the company discord over the last couple of weeks so they might not be too far away.
Just don't expect any Tsunderia members yet, I don't know the exact source but apparently as part of the agreement that the talents made to keep their models they promised to not resign to another agency for 6 months (how a now defunct entity can even uphold this I don't know). If it is true I wouldn't be surprised if they did another Invader wave later in the year if any of them wanted to join.
Rrats were being passes around that the AirAsia chick is this one.
I don't think it's been confirmed though
