Oh, yes, we've been thinking about it, eagerly, even though other things (modules, true polymorphism, value types, native interconnect) keep pushing to the top of the list.
Most recently, at the JavaOne "Ask the Architects", we were asked "what big-ticket item would you add to Java that is not already on the map?" Mark immediately said, "coroutines".
P.S. ...Which relieved me of the duty to say "coroutines", allowing me to talk about a group of overlapping DSL-like features like object construction expressions, complex constants, builders and complex array selection expressions. Those things all fit together, you know.
