We probably won't. The vast majority of Gridcoiners run PPS Sieve subproject, because it yields most credits and therefore most GRC. You can't discover new prime-numbers by running PPS Sieve, you are just doing a lot of preparation work - searching and discarding lots of non-prime numbers, so that other subprojects have less to do, focusing on numbers which look like promising candidates for primes.
