I don't think Perl 7 will be a thing in anyone's planned future. There are now two languages in the Perl family: Perl 5 and Perl 6. Perl 5 is still developed, has yearly releases and feature additions. Perl 6 is a brand new language that just had its first release. There is some history involved in why it took 15 years and why it's named "Perl" and not something else, but it's an entirely new language.
