Levin Rambin's Percy Jackson's release date has been pushed to March 2013!
According to Collider:
Fox has pushed Percy Jackson: Sea of Monsters back all the way to August from a previous March 15th date. The film currently faces no opposition on its opening weekend, but opens one week after Sony’s Robocop remake. The majority of the first film’s cast returns, led by Logan Lerman, but Thor Freudenthal takes over directing duties from Harry Potter helmer Chris Columbus.
