Well, I finally got around to taking some pictures of the great room, and I thought I'd post them. Yes, the 27" Sony is a joke in that room, but according to my wife there are lots of other things to come before a new TV.
Eventually, the plan is to put a fairly large fireplace where the TV is now, and move the system into a "true" theatre in the basement. But that's a long ways off.
As you can see, the only place for the QS8's was on the back wall. This works amazingly well and I'm quite happy with how they sound there. I've never heard a set of 8's on the sides where they "belong", but for those of you who can't put them there, I wouldn't worry - you'll be fine at the back.
We still need to get an area rug in the middle, but all the ones my wife likes are 2 to 3 grand, so consequently - no rug.
