This project cost £2.5 million.
Kepler answered 'how common are exoplanets'. This project will answer 'what are the easiest largish exoplanets to observe'. The TESS satellite, launching in summer 2017, which is much the same as this project but done from space at about a hundred times the cost, will produce a complete catalogue of exoplanets around bright stars, down to half the size of the ones found by this project.
The problem with Kepler is that it looked at such faint stars that it took inordinate effort to follow up the results; if you find planets around significantly brighter stars, you can do radial-velocity follow-up with moderate telescopes (which confirms that you've found a planet rather than a sunspot of unusual size, and tells you whether there are other planets in the system), there's the possibility of doing differential spectroscopy from space to find out what their atmospheres are made of, and if the stars are bright because they're close there's the possibility of directly imaging the planets with things like the Gemini Planet Imager.
