Maybe it is a good idea not to add another view. I'm however a bit skeptical if we can find a good way to bring the staging concept into the synchronize view. The synchronize API supposes a local state (L), a remote state (R) and a common base (B). 
L     R
 \   /
  \ /
   B

Staging supposes a different topology (Local, Stage, HEAD):

L
 \
  S
   \
    H

So we put a concept into the view which is not made for that.

I also think that the synchronize view is made to view the difference between local changes and changes on something that can change itself, be it a remote server or another branch. Therefore it is useful to prepare a commit in a centralized versioning system like CVS.

In git committing is something different. It is a purely local operation. You are sure that there are only outgoing changes compared to your HEAD. In git you additionally have the index in between.

When I see all that I think that staging and committing in Egit should be done independently from the synchronize view. Nevertheless it should be possible to trigger the commit dialog or the staging view from the synchronize view.
