I bought a Panasonic plasma display which can be upgraded with a DVI/HDCP module. I've read some technical articles on this but I'm still not sure exactly I would need it now, in the future or ever. I don't want to not get it and then need it later when it is no longer available for my display. Is there any advantage to having this interface for the near term? Will HDCP eventually be mandated? And wouldn't that make a lot of existing equipment unusable? I'm looking for some laymen type opinions on this topic and not just being pointed to more techical white papers.
