What happened to the Kyuubi's chakra after Orochimaru releases the Dead Demon Consuming Seal?
As of the current chapter (630), it is still not known if the Kyuubi's chakra was released from the Shinigami's stomach. It is possible that it is the gift that Minato is referring to when the kages and Sasuke's group are about to go to the battlefield.
