Okay, I thought I'd acutally make a post like this since I've been making theories about Shippuden throughout the year, hehe.
Looking at the past few chapters, I already had a suspicion when Sasuke freed Suigetsu and suggested that there were three more people to recruit. At first, I didn't have anything to work with. But when they got Karin from the south, however, I finally had a working theory.
Most, if not all anime find a way to fit the Four Chinese constellations into the plot. Naruto Shippuden, I'm thinking will be no different.
Suigetsu......................WATER element, was held captive in the EAST
Karin...........................unknown element, was held captive in the SOUTH
Juugo..........................unknown element, held captive in the NORTH
Sasuke's next recruit.....unknown elemet, most likely held captive in the WEST
Look at that, EAST-SOUTH-NORTH-WEST. Thus I am making the presumptions that Suigetst = Seiryu, Karin = Suzaku, Juugo = Genbu, and Sasuke's next recruit = Byakko.
And there you have the four symbols of the Chinese constellations. Not sure of what importance it will be yet due to the lack of information given in the manga, but I think there will be a ever-frustrating long chapter on its explanation if I'm right about this.
Sorry if the serious Naruto discussion freaks people out, but that's me, as

and

would know. In fact, the serious Naruto discussion freaks

out, since she just got into Shippuden, so...yea, hehe.
That's all for now! Look forward to more Naruto Shippuden Theories/Predictions in the future, 'cause I have been watching waaaaaaayy too much tv and movies which has given me the gift of predicting plot twists and such before they even hint at it.
