For Mirror's Edge 2, DICE hired experienced parkour-ists to wear GoPros and do their thing, to try and get a more realistic look for the game. But judging from the presentation, it looks like they're just getting started. The documentary-style video EA put up on the screen had developers talking about the game interspersed with early footage emblazoned with "conceptual prototype" labels.
DICE says it has gone back to the drawing board with the new title, rethinking the character, the combat, and the controls. But, from the snippets of footage that was shown, it certainly looks like it'll please fans of the first game, with extremely similar environments and animations.
