The end of doctors with multiple endorsements?

With training posts becoming increasingly out of reach for FY doctors, could we see the end of medics switching specialities also?

I know a consultant who holds MRCPsych, MRCGP and MRCOG. You might see someone who has done GP training and then gone on to do another speciality but what are the chances we'll see a consultant with more than 2 endorsements in the future?
