Hey, I watch the anime and keep tabs on the manga (thank goodness the chess match between Sasuke and Itachi is over).
They released episodes 51 and 52 last Thursday, but was pretty dissapointing coz most of it were flashbacks from the first series. It seems like it's not the first time the Kyubi has met an Uchiha. Hehehe.
Oh, and the "fight" with Sasuke was great. Shows how much Sasuke has improved and can't wait to see how they put into anime his fight with Orochimaru.
