Battlefield 3 was first mentioned in June at a conference by EA COO John Pleasants. At that time, Pleasants also revealed a Criterion-developed Need for Speed game, which was announced again during EA's latest financial conference call -- so Battlefield 3 is somewhat of an expected property, lending credence to the existence of Mirror's Edge 2 by association. The last we heard about a follow-up to Mirror's Edge was that a "small team" was working on something back in June. Carlén could be part of that small team.
It's possible, given EA's recent layoffs and turn toward more surefire franchises, that Mirror's Edge 2 did exist but no longer does. We're checking with EA to verify the information found on this portfolio and to determine the current state of the franchise.
