This is promising. Obviously, it's easier to use this method to detect a known exoplanet (one that is big, with frequent transits, across a bright star) rather than detect a new exoplanet (even a big one with frequent transits across a bright star) ... but it's promising all the same.

Especially since it's a proof of concept, and I suspect small hardware upgrades would make it more effective (thus, more able to detect new exoplanets, in the right conditions).
