Here is a recent video from "Quantum Gravity Research" (not much new information)

(View video on YouTube)
It criticises String Theory saying it has "kind of failed" (9:10) and has "never produced any successful predictions".

It talks about E8 and their "friend" Garrett Lisi.... here is an E8 explorer he has been working on:

I think E8 predicts some particles.

QGR has 130 videos on Youtube

and 10 staff members:

What do people here think about E8, String Theory, QGR and possible contenders for a theory of everything (or at least combine gravity with QM)?
