Well, that is certainly what this image seems to imply but is that confirmed fact or misdirection?
It's probably still Earth 2 Kara aka the New 52 one. It's just now they did away with the new 52 costume and slapped the old one on it. Though now people will hate the fact the personality's still don't match from Winnick/Gray/Palmiotti/Conner version.
So I'm all for the return of that version plus the dumping of new 52 Terra and the return of Atlee version. Just so much better then the oblivious traitor version who should remain dead and as she was.. a traitor.
