Yes, I'm afraid it will get ugly again for some people and it's hard not to match. People can say whatever they want but that sequence (not matching, scrambling, going to a place I didn't expect or really want to go to) was one of the most stressful I've ever been through.
It's funny that you ask, though. I just met with the peds pd this week at my current institution. I'd looked into reapplying but found it to be even more competitive than last year. But I'd like to be academic and I was afraid things might not go my way again- even if I matched I might not be at a strong program or might not match again. And I like my program a lot. Not what I would have ever guessed, but the attendings are nice and I've been invited on team dinners, to an attending's house for thanksgiving, and have frequent outings with my cointerns. And there are lots of research opportunities. So staying seems good. I was discussing this with the peds pd and she said I was welcome to do electives in peds and do research in their dept if I want. And that I could apply to peds later if I want. My PD has promised to help me do this if I want in a few years. I think Medicine then peds is possible and what I'm hoping to do, but I might decide to just stick with medicine. I think I'm at a particularly supportive program/institution, though and one with funding. My PD checked and the GME office said I'd be covered for 6 years if I so desire.
That said I wouldn't recommend it. It will take me 6 years, will require me to do another intern year, and keep me out of peds then medicine for 3 years, although the peds pd here pointed out that I could do electives in combined specialties.
I'd interviewed at some of the top programs last year and had good feedback from them, but also had a fairly broad list. To not match was tough. Things worked out though. Good luck to you guys!
