Jeff Brown, as quoted on Code To Joy: Scala, Erlang, and Haskell should be on your list for experimentation, and, well, Groovy and Ruby are simply required.
I'm glad to see the list of hot languages keeps on evolving.
At the end of the day, it is what people can do with a language that drives the adoption of a language.
The mathematician in me applaud any language where functions can be defined the most natural way:
hyp(x, y) = sqrt(x^2 + y^2)
Scala and Haskell comes really close to the ideal. However to popularize these languages, something that is uniquely doable in them has to be invented.
The sudden prominence of Erlang is the result of the "It's the end of the free lunch" multi-core scare from Hurb Sutter. It's all the rage in the blogosphere.
As to the Groovy and Ruby comment, I think a more accurate statement would be "Groovy or Ruby is required." I would have thrown in another disjunction "or something like them," but that would make the statement too crowded.
