Most likely he will not be updated. No info but he was a support for the newer Sasuke. He was still in his PJ's and did the same support as previous installments. --- Sarcasm Imminent http://i.imgur.com/2xdIc.gif
I'm sure he will remain the same. If Sasuke's team had the cloaks on, then Karin would have been seen wearing it in the trailer and pics of being Sasuke's support in the hack-and-slash mode that was just released.
I want to know if Orochimaru will get an update or not but i have not seen anything about him on Storm 3 yet. Atlest he needs a way faster grab because his old grab is really slow and is extremely easy to avoid and he needs a new and better jutsu that actually helps you win. His jutsu on Storm 2 and Generations is completely useless.
CC2 really need to give him new attire, the vagrant look doesn't do it for him. --- "We live amidst a silent storm, leaves us unsatisfied at best, fill your heart with what's important and be done with all the rest"
