The plan for Perl6 is to eventually run Perl5 code with the `use v5` statement. You just don't throw 30 years worth of CPAN into the garbage bin. Meanwhile, Perl5 is being actively developed, new minor versions are released at least once a year, people are actively improving the language via extensions and even the core is evolving slowly but steadily. I don't thing it will be abandoned any time soon. Perl6 is being developed separately, mosty by other people.
