That´s funny, because I saw this the following page in which what you just have described matches the definition of "what now?" [seria: o que (é) agora? @#!$*?!#%* ]http://www.writersevents.com/Words_Star ... ition.html"what is wrong now?"
Of course, I may or may not be mistaken on that one. Since I am not the sharpest knife of the drawer here, or anywhere else, for that matter.
If I am it´s not a first in my career.
So, let´s wait further comments from natives or more advanced learners.
Ah, second tought here. Re-reading it, sounds like you are right, so both ways could mean it.
So, you might be right; certainly.
I must be right too, and again "now what" is statistically more common, just make a search on any search engine.
