McCoy does call for Chapel at one point during the movie, so I don't think they're adverse to introducing her in future installments.
Like many people said, however, I hope we don't have any schmoopy, mopey triangles going on. (Please no Spock/Uhura/Kirk... pleeeease don't do it, no matter what Zoe thinks!) Since it's unlikely that Chapel will have much time onscreen, if she were pining after Spock, it's probable that she would again be defined as a character by her unrequited love. Isn't it enough to show a woman who's a good nurse and truly cares for her patients? I personally hope she has no romantic interests that we see. Or let someone (not Spock) pine over her for a change, if we must...
