Oh absolutely! By monitoring ~200,000 stars continuously are able to measure small changes in the brightness and spectral shifts. That will then be used to predict the presence of orbiting planets. The resolution will be so great they should be able to find Earth-like planets. Unfortunately it will only find them if they are orbiting in a plane that is near edge on to us. That is limiting but still much better than anything we have so far.
Shall we take bets? I vote in 2 years they will find 50 Earth-like planets.
