Hi Dan,
Camera raw will probably not be added to Premiere Pro because it generates files that are too difficult to edit with. In Premiere Pro you can adjust Source Settings. If that is not enough control, you can always import them to After Effects where you can use Camera Raw. Then, export files that are high quality, yet are still able to be edited. Sorry if this is not exactly what you wanted to hear. If you'd like more parameters to be added to Source Settings, feel free to make a feature request: http://adobe.ly/feature_request
Thanks,
Kevin
