Travis,
Nothing doing yet for true 9.1.
The new Yamaha is set up like this:
YAMAHA RX-Z9 9.1 Home Theater Surround Sound Receiver
9.1 Channel, 1290 Watts (170 Watts x 7 + 50W x 2 )
The last two are used for a different zone or bi-amping. When 9.1 does come around, you'll need a long room like a movie theater, and more surround speakers will be put on the wall for an "enveloping effect." Don't hold your breath though for movies to do that for a long time. 7.1 only matrixes the rear channels, you only really have a true 6.1 system for now.
