Bendis wrote Ninja, just saying.
The statement you highlighted doesn't suggest Bendis DIDN'T write Ninja. It suggests Ninja came out before Bendis started writing on Daredevil vol.2.
Where writers are concerned, Bendis is the only one that forced me to stop buying DD. I'm sure his were good after I stopped but his writing was not to my taste. Just found it very hard to follow. (Yes, I do own Ninja and it's really bugging me were he used the Korean/South Asian language as I cannot find a translation to english for it.) I also would like to know if anything came of the child Karen yet. (mentioned this somewhere else to).
Oh yea, I happen to like this new direction so far but it is going to depend on the next issue if I keep buying.....I'm hoping I'm wrong.
Bendis stopped writing DD in '06. Also last I checked Baby Karen doesn't appear nor is she even mentioned outside of Guardian Devil.
