Scala - Replacement for Java?

Great blog post on Scala at http://macstrac.blogspot.com/2009/04/scala-as-long-term-replacement-for.html. After playing with the language for couple of months, it seems the concepts are really catching up with the developer community and the prospects of retiring Java a real possibility. The language is simple, elegant and potent. When combined with a strong user experience front like Adobe Flex it can really shine! I am excited about the possibilities.
