Adobe has not announced any plans for releasing the Touch Apps on the PlayBook platform. Unfotunately, we can't comment on unannounced products because of company policy. I would recommend creating a feature request if it is something you would like to have avaiable. That way our developers know we have customers who are interested. Thank you for posting, sorry I don't have more to offer.
