A quote from Dan Didio (courtesy of Newsarama):
The second one – the illness of Karate Kid, and his search to find a cure. That’s also going to take us on a key road that is integral to so much that goes on in Final Crisis also, but there is a definite resolution to his story in this book too.As someone who dropped Justice League of America until Brad Meltzer left the book, and didn't feel much more for Geoff Johns' revitalized Justice Society, I read none of the Lightning Saga... which is where, to my understanding, a great deal of the Karate Kid story has it's roots.
The problem is that almost none of it was explained within the pages of Countdown. How is he sick? What are his symptoms? Why didn't he make an appointment with Dr. Mid-Nite like the rest of the DC Universe? (Was he too busy, aherm, 'examining' Power Girl again or something?)
As someone who only read what was published within Countdown of this story, I knew almost nothing relating to it. That's kindof a problem.
