Scala's concurrency model is based on Erlang actually, although the Scala actors are not OS independent like Erlang, but the message passing mechanism and the concept of light weight processes independent of each other exchanging messages( no shared states ) is common to both. Scala runs on the JVM so its much easier to integrate it with huge java projects, and its performance is comparable with Java, and its being promoted in a big way by many of the big names in the industry. I see scala being widely accepted, whatever little I've used of it, I really love!

Scala's actor library emulates a subset of Erlang's message passing capabilities, but it's far from what Erlang has to offer. Scala's actors are not distributed, they don't have their own heaps (Erlang processes do, to minimize garbage collection sweeps for soft real-time performance), they aren't preemptively scheduled by the VM (the only preemptive scheduling is done by heavy native threads), and they don't have "shared nothing" sematics because Scala lets you send pointers mutable objects between processes. Furthermore, Scala doesn't have hot code swapping or Mnesia, both of which are essential for building scalable fault tolerant systems in Erlang.
