If I reserve today for the 950/770 combo, about how long should I have to wait for this?

Meaning is it weeks, or months? Just wanting to make sure I keep my money handy but also would want to put it to use somewhere else if I don't need it for a month or two as well.

Also, How does this compare to the Sony TA-E9000ES? This is what I have currently. I was wanting the upgrade for the 7.1 Surround capabilities since more and more DVDs are coming with it. I will be hooking this up to the Klipsch Reference speakers (RF-3, RC-3, RS-3, and I guess two new RS-3s)

Thanks

Tom
