Still no indication if this is a prequel to Reloaded/Revolutions or some convoluted sequel that brings them back.
Neo's fate was a bit open at the end of Revolutions, presumably he merged with the matrix code at the end and may exist in some form within it.
Trinity however was quite sufficiently KILLED in Revolutions outside of the Matrix.
Neo could be the new Oracle, existing as pure code. Maybe they used Trinity's template for a new agent.
