Looking at techniques, tools and trends for observability of distributed systems, becoming a lot more important with the push to the cloud and serverless deployments (when in most cases there is no local environment, and the key risks depend on service providers, platforms and collaborating APIs).

Looking at techniques for testers to teach developers how to test, patterns and ideas organisations around the world are doing to scale the testing beyond just the testers, and get developers involved in doing the majority of the testing. 

I would talk about techniques such as the ACC matrix, specification by example and pair testing.
