Yes, there are many more features to come, but they don't look like they will be as important as lambdas (and default methods) for everyday coding.

Thanks for the links.

I think you underestimate you important some of those are.

Specially for people doing big data analysis in JVM languages or jumping out of Java to languages like C and C++ for the last performance increase.

The Java community is so large that these are important communities in themselves. But they're still subsets. Someone writing a portable Java library isn't going to want to call into native code or rely on specific hardware. Changing the language itself affects everyone.

If you bothered to follow the links, they imply language changes.

I did, actually. Value types are nice but annotation processing can do pretty well:

I'm honestly not seeing as big as lambdas (or generics in Java 5). If you think they really are that big, perhaps you could explain why?
