With even Ford talking about making the next-generation Explorer a unibody design instead of body-on-frame, I have to say that Kia's decision to introduce a body-on-frame SUV doesn't make much sense. In my experience, the sort of people who used to buy vehicles like this for daily drivers are now buying vehicles like the Hyundai Veracruz.
I would like to see them introduce a pickup truck though. And how hard would it really be, as long as they've already got this body-on-frame platform in production? And it'd probably help them recoup the platform's R&D costs, since I can't imagine the Borrego itself will succeed.
