I believe Sinestro would not only need a very far apart starting distance to have a chance, but he would have to get her by surprise to have any sort of a chance. I still think Diana has this one in the bag though, she can break his constructs and eventually get to him and break his ring too.
I've always thought that Wonder Woman should be right behind Superman not only in sheer strength but in all-around fighting skills and maybe even as strong or stronger in certain situations, like against magic or where kryptonite is involved. And Power Girl and Supergirl should be stronger in sheer strength but Wonder Woman's fighting skills make her the better fighter.
I think that Wonder Woman has got some defeats that she normally would not have got only to make more of a story -- see if Wonder Woman mops the floor with everyone, then why do they need Superman? Just my two cents, I know 100 people will disagree.
Earth 2 was the only thing stopping DC from reverting about the old universe with Robinson off the book and gone from the company. I guess his crossover planed for next year is off and to me this means DC is rebooting again after Trinity War.
Good point. I doubt they will revert though, they've simply got too much invested into the New 52 to just go back. But I wouldn't be surprised if a Flashpoint 2 happened that sort of set everything back after a fairly long aftermath either.
