This depends entirely on what sort of contracts BioWare and Microsoft had in place. EA will have to honor those contracts. If there weren't any contracts - or if those contracts were only for timed exclusivity, and have since expired - there will almost certainly be PS3 ports in the future.
(My bet is Microsoft has exclusive contracts for the entire trilogy, but I have no evidence to support that.)
