I am not a physicist, but I listen to a lot of technical lectures from the institute of advanced study and other universities that post their colloquia on youtube, and the impression I've gotten is that string theory has pretty much fused with quantum field theory. A lot of the people in the string theory discussions identify themselves simply as field theorists, with string theories being just another set of concepts in their model-building tool box.
