It's tough to go out on a limb and predict the future, but I think Perl's future is relatively bright. The major issue with Perl today is that however ground-breaking it once was, it's now showing its age.

Perl 6, on the other hand, is finally becoming a reality, programmers are developing in it (well, Pugs, that is) and it is a language many of us have longed for. The language isn't out and already brentdax is building a content management system for it, there's a decent size module list and a really slick virtual machine that plays well with others. I believe Parrot, along with Perl 6, is going to be a huge force in the programming world. Naturally, I'm quite happy about that :)
