However, looking at the average from a large group is probably more informative than the EPA numbers that are generated from a very specific protocol that still doesn't really reflect the real world, but it will be a while before we have much of that data.

Maybe the car will be so fantastic I wont care. If that's not the case, might wait a bit.
What's achievable is like trying to predict your finish time at the Boston Marathon from the winning time. Same thing with using a large group of averages, you can't predict your mpg by that just as you can't predict your finish time. You need a reference to your specific driving and the best you got is your current car and it's mpg vs the EPA. Turbo car or not shouldn't make a difference here.
