I think that it is YOU that doesn't understand. Shisui was pushed out early because it earns them money. Anything that comes out EARLY is always tied to them making money. Updates that were promised to the players that doesn't earn them a profit are put on the back burner......

Yeah, let that sink in.....everything that they push out early is meant to milk you for all you are worth. Even the release of Edo Tobirama was ahead of edo hiruzen and Angel Konan. There is a reason for that.....Edo Tobi isn't used nearly as much as edo hiruzen.....so they release him first to squeeze more out of the players before releasing the ninjas that will make him less desirable.

The simple fact that you and people like you can't grasp the simple concept that their bottom line is Priority 1 vs even fully updating 3.0 features (yet we are in 4.0 now) speaks volumes.
