We have a whole arsenal of old antibiotics no longer in use that are candidates for redevelopment. As bacteria develop resistance to newer antibiotics they make evolution tradeoffs which bring back into play older antibiotics.
I think cocktails will be used (if they are not already in use) to attack the bacteria from different angles at the same time reducing the likelihood of developing resistance.
Another thing is better protocols. More quick testing before prescription so you use more targeted antibiotics and reduce the use of wide spectrum antibiotics.
