@ Subash: I think it does kinda make sense Kenpachi is not back yet. After he won the fight, he got distracted by the voice of his zanpakuto, which/who was calling out for him (chapter 527). As Kenpachi has regretted not knowing the name of his zanpakuto ever since he fought Ichigo in the Soul Society arc (chapter 114), it would make sense that he went after it and would start some sort of training. Unless he is to be the only Captain without a Shikai and Bankai. Well, I guess Kenpachi having a Bankai would mean instant annihilation of Soul Society, but that aside ;)

At times, something I kinda struggle with myself is the timing issue of Bleach. Often it is not so much because of Kubo, but it's more that the manga is updated once a week. I mean, as of now I guess Ichigo is still traveling back to Soul Society from the Soul Palace and the last time we saw him was like half a year ago. It was said it would only take 7 days or so to travel back. I guess it would be kinda likely that Kenpachi hasn't been gone for that long either, at least Soul Society-time-wise.
