One can always hope, but there is a serious limit on the availability of telescope time. Even if the transit method was much more productive than it has turned out to be, the number of new discoveries couldn't be dramatically higher because each discovery must be confirmed by measuring the radial velocities. Large majority of promising candidates turn out to be false positives, unfortunately.
