I mean the plan with Eva according to Anno is to do like what Gundam does. i.e. you have you main timeline (Universal Century) with focuses on different groups on opposing sides of the conflict during different periods. But then you have your many other offshoot series (00, IBO, GWitch, SEED, Turn A, etc) that are free of the main established canon while keeping the same core elements to the series.
