Thank god for a sieve-like memory. I watched the OP twice and I still don't remember what was spoilerish about it :P

Not only did Jiraiya obtain frog-like properties, but he also required the two Elders to perform his technique. Let's see what Naruto can do.

I wonder how well the Rasenshuriken will work out. They mentioned increase recovery and all, but it doesn't dismiss the fact that using that move will cause microcuts in his arm, severing the chakra channels there and stopping him from moulding any more.

Unless he uses this natural energy to create some sort of barrier over his arm, increased regeneration won't let him recover what supposedly can't be regenerated anymore.
