The promo was vague but I rather get Morrison's Action Comics and the Authority run as the tone for this reboot.
Embrace the weird history of the Silver Age and the Rabble Rouser spirit of the Golden Age.
Having Supergirl be from new Krypton and looking for any new survivors would be a cool take.
Having Mr. OZ be Kru-el could be fun.

I still rather skip Clark and go for Conner but I'm still hoping Gunn wins me over like Reeves does.
