There have already been several BD titles released with the ICT. The specific titles escape me but I know they’re around.
There’s another wrinkle in this as well, since the BDA requires that existing players will be updated via firmware to restrict component outs to 480. That change would come with one of the usual updates that includes new AACS keys.
I think it would be logical to assume that all this has nothing to do with content protection and everything to do with selling new hardware.
