Didn't Itachi or Kakashi say that there are 3 people now with the Sharingan eyes (not including Kakashi..)?

Perhaps that guy in the last panel with the Sharingan like eyes is another Uchiha? I dunno, it's probably just Itachi.

As for the Akatsuki guys..

In the back is a huge guy who we don't know.

Someone and Kisame are in front of him. The guy we met a few issues ago is hanging upside down.

Itachi is standing under him.

Also look at the guy with the weird eye's hair..it's more like Garra's not Itachi's. I don't think that is Itachi.
