In Bleach, whilst watching the final fight between Ichigo and Grimmjow, I noticed that Grimmjow's body did not vanish when he was defeated as the other Espadas did (in the aftermath when Nnoitra appeared). There is no mention of Grimmjow after this. Confused, I turned to the manga, in chapter 286, I could not tell either. I was still confused so I turned to the wiki. In the wiki, it vaguely says
"..but Ichigo steps in and protects Grimmjow as he lies on the ground, severely wounded. However, he survives the attack...
A quick Google search and I found this (dead) Yahoo! Answers post about this, but both posts are vague and unhelpful.
Is there some credible source that can verify if he is alive or not?
