How can I show a preview of all the data entered as the final step of the django form wizard?

I use the form wizard in django 1.4 to conditionally add instances of up to seven models. No matter what steps the user has completed, I would like the last step to show a preview of all the data entered. It should not be a form, as the user can use the "First Step" or "Previous Step" buttons to return and correct any data that they messed up. I would also like to send a confirmation email to the user with all their data, and I suspect that any solution I came up with here will provide the data for this.

Here I have:

# views.py
FORMS = [
    ('person_application',  PersonApplicationForm),
    ('family_application',  FamilyApplicationForm),
    ('student_application', StudentApplicationForm),
    ('spouse',              SpouseForm),
    ('child',               ChildFormSet),
    ('roommate',            RoommateFormSet),
    ('preview',             Form), # only doing this because I think FormWizard requires a Form subclass for every step, which makes sense
]

TEMPLATES = {
    ...
    'preview':              'preview.html',
}

condition_dict = {
    ...
    'preview': True,
}

class SignupWizard(SessionWizardView):
    ...

    def get_context_data(self, form, **kwargs):
        context = super(SignupWizard, self).get_context_data(form=form, **kwargs)
        if self.steps.current == 'preview':
            context.update({'all_data': self.get_all_cleaned_data()})
        return context

    # # This is triggering an infinite loop or something because python gets stuck at 100+% cpu and won't stop even when I kill runserver
    # def get_form_initial(self, step):
    #     if step == 'preview':
    #         return self.get_all_cleaned_data()
    #     return {}

    ...

# urls.py
urlpatterns = patterns('app.views',
    ...
    url(r'^start$', SignupWizard.as_view(FORMS, condition_dict=condition_dict, instance_dict=modelform_instances), name='wizard'),
    url(r'^thanks$', 'thanks', name='thanks'),
)
