The last release of Rakudo (Perl6 on Parrot) was in July: http://rakudo.org/2011/07/29/rakudo-star-2011-07-released/

The next release is due soon and this includes some heavy refactoring so will be a lot quicker: http://rakudo.org/2011/08/19/rakudo-2011-08-release-status/ & http://rakudo.org/2011/09/09/nom-branch-default/

Perl 6 is an entirely different language than Perl 5.14 with an entirely different development path. I don't see Perl 6 as "the next version of Perl". Perl 5 continues to thrive and will for some time.
