Based on the bit of feedback I've seen posted by from last weekend's Dallas get-together, it appears confirmed that there is no lip sync delay. It wasn't clear to me how the delays are being handled, though, so I'm also looking forward to some more information in that regard. It could be that all four of the rear channels share a single delay (which would exactly match the 950's arrangement). Also, I think the bass management is limited to a single fixed 80Hz crossover. Our own JeffreyMercado is due to take part in the public beta test, so I suspect he'll be able to answer
