Ken:

Even knowing the amount of processing required doesn't really mean much. If the processing exceeds what's available, then they're screwed anyway as that's a DSP upgrade.

With Ms distributed processing architecture, they do have an edge as they might not need to touch the DSP core. I don't know yet.

However, I believe that you are being quite unrealistic with your expectatons. Why? Because you can't know the amount of processing required without knowing the specifics of the codec. They do have a tremendous advantage when it comes to Dolby TrueHD, but with DTS-HD they're pretty level on the playing field.
