As we march our way toward the land of diminishing marginal returns in medicine, crop science, etc., not all the news is bad. The system is dynamic, which is what makes absolute predictions fail so miserably.
Research led by a team at Harvard are starting to crack the code to the resistant bacteria, and find out what exactly it it that is making them so resistant.

The genome sequence gave us unprecedented insight into what makes these highly resistant bacteria tick. Several things were remarkable,” says Gilmore. “Vancomycin resistance repeatedly went into just one tribe of MRSA, so the question became ‘what makes that group special — why did they start getting vancomycin resistance?”’
“What we found was that this group of MRSA has properties that appear to make it more social, so they can live with other bacteria like Enterococcus. This would allow those MRSA to more easily pick up new resistances,” adds Kos. “The good news is that some of these properties weaken the strain’s ability to colonize, and may be limiting their spread.”
