Gooch, are you limited in what your tv providers might be? (only one cable/fiber option, tall trees or HOA prohibiting dishes) Direct TV's wireless boxes work well and make this problem kind of a non issue but Dish's and AT&T's kinda suck in my experience. If you don't have a lot of options here I would safe guard by going overboard on the wiring during construction. If you are in a new area that has crap for high speed internet you will want to hardwire everything to make most of the bad ip. This may really become an issue if Trump lets us all get mumped over on the net neutrality issue.
Low voltage wire is super cheap. If there is any question that you may eventually use it, put it in. I mean, a 1000' roll is like $280 and two ppl could basically wallpaper a house in wire in a weekend.
It's all very cheap and easy - coax, speaker wire, power - to run during construction and I would rather have it and not need it than the alternative.
My over the top advice -
Every possible TV location (Master Bath, Garage, Patio, Pool, Hot Tub, etc)
Power, coax, HDMI and 3 runs of cat 6- one for the network and two for use possible HDMI extenders or whatever next gen thing might be coming.
Also run a pair of wires anywhere you might want speakers and run 7.1 in the main tv watching areas even if you don't plan on using it - you never know what hobbies you might develop in your old age
