dbhally- The point is that considering CS has only the 747 to do in the Boeing line (the 787 hasn't been out long enough and they likely will skip the 717 because it's really not Boeing and not particularly popular), CS has options on what to do next. Perhaps they've already decided, but as you may have noticed, they don't really like to say what they're doing, so there's no way of knowing. And you say they've done their market research. Well, isn't market research finding out what people will buy? Now, it seems to me that a TriStar would be very popular indeed (I personally would like to see an A330, but most people are requesting that a TriStar be made).

Now, as I've said multiple times before, they have a 737 and 777 to do, so whatever they decide on to do next (which I personally believe will be a 747, but I could very well be wrong) will not be known for a while.
