You're very close. The post-increment operator (as in $i++) returns the current value and then increments the value, while the pre-increment operator (as in ++$i), increments the value immediately and returns the incremented value.

In this case, however, I don't think you even want that, as it will mess up your counter. All you really want is $i + 1 (untested code follows, note that this will mess up on the last output, since nothing follows 'betty'): 

my @array = qw( wilma fred barney betty );

for my $i (0 .. $#array) {
    printf(
        "We have %s, while %s is next.",
        $array[$i], $array[$i + 1]
    );
}
