I doubt developers ported to the PS3 out of the goodness of their heart, particularly in the case of Bioshock (who's sold pretty well). Since we have no problems saying Microsoft paid them, and I doubt a company would port to a more difficult-to-develop-for system if they were not given incentives by Sony to do so.
So basically my answer is, no they won't stop.
