I found some more character info from DC Comics.com today regarding the upcmong comic book series Earth 2.

For those of you looking forward to the new comic book series volume of World's Finest (starting in same month as Earth-2), this series will feature an exploration of the Helena Wayne of Earth-2 before getting stranded on the main DCnU and becoming Huntress there. According to World's Finests editor Will Moss, this woman will be portrayed as having maintained the mantle of Robin during her time in Earth-2, fighting crime alongside her father the Batman in the same manner the (main) DCnU Batman currently fights alongside his son the Robin (Damian Al' Ghul). Reading about this makes me wonder if the post-Infinite Criis Earth-2 was merged with another universe as well as to explain what her Helena's life as Huntress in that universe, but hopefully, the new series will explain everything to save us, the readers the trouble of feeling too confused about what happened throughout in main DC Universe continuity.

In addition, Earth 2 will feature a Wonder Woman of Earth-2, but unlike the (main) DCnU Wonder Woman, she is the last of her kind (the Amazons) in the similar manner of Superman once being called "the Last Son of Krypton" within the timeline of the Post-Crisis DC Universe (what we come to know as "New Earth" after the run of Infifnite Crisis) before reality alteration by the events in Zero Hour - A Crisis in Time.
