Well now that Shizune has figured that the black rods are chakra demodulators, you can bet your ass on it that they are going to bust out with some sort of chakra 'scrambler' and block the chakra waves from travelling in the air.

I think the people best suited to fight with the 6 pack of Pein will be the Hyuuga, as a lot seems to revolve around the fact they are interlinked and sharing chakra with each other. The Hyuuga should be able to see this chakra activity and block it off.
