Java has never been on the cutting edge of language features, instead the people behind Java take a long look at what works in other languages and takes time to implement these features in the best way possible. For example, Java 8 lambdas expressions use invoke-dynamic. The behind the scenes implementation allows lambdas to be extremely performant and at the same time allow for future improvements.
Venkat then went on to talk about upcoming projects in Java: Project Panama, Project Valhalla, Project Amber, and Project Loom, which I will not go into right now. This talk was both entertaining and informative (Venkat uses metaphors and jokes sprinkled throughout his talks).
Although this is a large change in the Java language development cycle, in the end this is a good thing because it will encourage Java developers to update more often and spread out new features over more time, not bundling them all at once.
