What should be the new features in the next generation programming languages?

We have progressed a lot in the development of programming languages from low-level to high-level and we have achieved program portability, platform independence, multi-threaded application development, database handling, network programming, web-based application development, enterprise application development, etc. We have also developed many programming paradigms like structure programming, object-based and object-oriented programming and many others. In this direction, Google is working on the development of next generation programming language called "GO Language".

I would like to know which features should be expected in the next generation programming languages?
