Ah OK, when you said "spec", I thought you meant from Dolby. Hardware implementation is going to be all over the place at first. Remember when PLII
x was first introduced? It ended up on plenty of 6.1 receivers, which nullified its main advantage (stereo rears) over EX decoding. Similarly, it may take a few models before we start seeing full 9.1-channel implementations of PLIIz.
