As to whether Perl6 is released: I guess I'll believe it when someone on slashdot writes "Perl 6 finally out", with the obligatory jokes about Duke Nukem Forever and "at least it reached 1.0 before GNU Hurd did". (N.B.: By 1.0 I mean "the first release wide number of people would consider production ready with no obvious shortcomings".)
As to the question about role, people with Unix heritage are likely to be quite resistant to anything that needs a JVM to run, so that makes Perl 6 unusable for traditional sysadmin tasks where Perl 5 was clear upgrade from bash, awk, sed, etc. I personally appreciate the idea of using JVM, because one really good thing about java is that there's a ton of good libraries written for this language, so that would immediately seed a pretty big "JPAN" for Perl 6. However, in order to *really* benefit from that, the usage of those classes should be as transparent and easy as humanly possible. And of course it requires an IDE that is capable of handling Perl6 while completing java types and method arguments... With 6, is it still true that only perl can parse Perl?
You see, I've griped before about Perl 6's reprogrammable syntax, or about overly complex syntaxes in general. It makes it hard for tools to work out what to autocomplete, where syntax errors are if the expression is not valid, etc. Of course, with reprogrammable syntax I guess any hope for parsing anything is lost unless your parser happens to be a Perl 6 compiler.
