Yeah, she does.
Pre-CoIE, Kara Zor-El was not as well-endowed as Kara Zor-L.
I expect the same to be true currently.
I'm not sure what you mean by "Yeah, she does". Saying Power Girl has the same curvy voluptuous look she had before new 52? She doesn't, at least not how she was drawn during the time when she had her own book by Conner and Basri etc. Was saying the current talk about Power Girl having notable voluptuousness, notably more so than other characters etc, is not currently the case in new 52. And that'd be nice to see, much like it's nice that Supergirl has a different body type than the DC norm, going both ways.
I wasn't saying that Supergirl and Power Girl look the same then or now if that's what you're talking about there.
These are not what you'd call a origin story, not in the sense that Superman, Batman, Wonder Woman, or Hal Jordan have.
I'm talking a full on mini that deals with her Krypton and the reason it was destroyed, plus her arrival on Earth Two, and her first year up until she met the JSA. Basically, I suppose an origin story plus the Year One treatment. Both of those stories were cursory at best.
