I think that if Ryanair did open a base in Edinburgh then it surely would have at least some effect on Prestwick. There are quite a number of passengers who use Prestwick that come from Edinburgh and the central belt. Prestwick Airport, I'm sorry to say, really has gone downhill lately. Overcrowded departure lounge, litter left from the night before, a cafe that looks like it was decorated by Lawrence Llewelyn Bowen and very expensive too!
