Geoff Johns has confirmed that he will be working with Kimiyo Hoshi, Doctor Light 2.
Which just leaves the mystery of why she was ever depowered in the first place, since it seems to have had no relevence to anything in the last year, and caused a big continuity screwup to no apparent purpose.
For a character who was created in the original Crisis the timing seems very odd that she should be depowered just before (in real time) the big sequel. Did some editor want her removed beforehand so she couldn't take part, or was Judd Winick the lone gunman who didn't bother to check whether she was scheduled to appear in the biggest companywaide crossover for twenty years that was about to occur? How is it then that she appears at all? Why is it that she subsequently appears in more comics than she had done in the previous five years, to the confusion of all the readers who assumed that she must have been repowered in a comic they'd missed? And will we now get a resolution to the storyline that's been left hanging for a year, or will one of Plotdeviceboy Prime's continuity punches have erased the whole thing?
After all, it wouldn't make much difference to any characters other than Kimiyo. Bad Dr. Light would still be a scumbucket, Green Arrow seemed to have forgotten her before the story was over, and Kimiyo's appearance was so lacking in continuity in the first place that it didn't make much sense anyway. We'd all just be left with a sour taste of a story that was bad, but which we'd still like to have seen the end of.
