I think people believe it will be around until King starts his Summer Batman event which is supposed to kick off at Batman issue #75. King's Batman is the reason for Dick having to be sidelined in the first place. So I'd imagine that it will be going on for a handful of more months past May. It will be close to a year of the Ric story sticking around since we first learned about it. Which I never would have guessed when this first started.
