There's always Scala, Nice (not much development going on), and a Haskell-like language called CAL. I was a bit skeptical about retrofitting closures into Java, but after listening and watching the slides of Neal's presentation I've become convinced that it can be done in a clean manner.

The problem with "a new language should emerge" idea is where does this new language come from? Ideally, it should have the backing of a Google, IBM, or Sun. I really like the Nice language, but I know that it sitting over at SourceForge pretty much guarantees non-adoption. Scala is in active development, but it lacks good Eclipse integration. That's another show stopper for these alternative langauges on the JVM. It can be the greatest thing since sliced bread, but if it doesn't have good IDE support in this day then forget about it.
