Bob,

I think it makes a lot of business sense for Dolby to enhance their DPL2 to 7.1 support.
Agreed. All the competition had already gone 6.1 (Circle Surround II, DTS Neo:6) or 7.1 (LOGIC7). By their own admission , they are a "latecomer to the 7.1 environment". PLIIx makes their offerings more competetive.

Best,
Sanjay
