No. They will do too little, too late. Just like the lambda that were slated for Java 7 and came in Java 8. Now they're talking about value types, but it will be for Java 10 at the soonest (Kotlin doesn't have that either btw).

They're also wont to misdesign a lot of stuff. The generics implementation is mental, and the module stuff from Java 9 seems to be a debacle in the making. Lambdas are good though.
