True. Though Catwoman replaces GCS, all three of those characters are still in books, so it's not a total replacement.

Though I don't read her ongoing, I am a fan of Power Girl (I can only buy so many comics T_T) and I'm sad that she isn't getting her own ongoing (unless they magically don't make action comics anymore, which I doubt). Hopefully they'll put her in the JLI until time passes for her to get her own ongoing again once some of the launch books inevitably fail.
