Well now, wasn't that an exciting new chapter? Crazy stuff the swordsmen use (and I'm glad I got here after the whole discussion), guess Kishi still had some crazy ideas he needed to get out of his head.
Also, I enjoyed the side-flashes (whatever) to Suigetsu and him finally telling us why he is so obsessed with the swordsmen. (So, his brother is a Stu, too. Puts his relationship with Sasuke in another light. (Oh no, the fangirls!))

The body switch thing confused me, too. But I forgot the Yamanakas could sense chakra as well... (Also, his name is really Santa? )

Finally: prediction for next week: Kakashi (or someone) will flame Zabuza for not caring about cutting off Haku's head and he will regret it and confess his love or whatever yadda, yadda; Haku will be happy, Zabuza will be happy and they will both be released. Or something to that effect.
