A 6-tuner box is a niche for individual box usage, but not as a whole-home solution. The primary purpose of these kinds of boxes is to do all the heavy-lifting for inexpensive IP STB boxes placed around the rest of the house. By and large this scenario reduces long term costs. This is where cable is going, so it'll be where Tivo goes. But sure, if someone doesn't want to go all-in with Tivo hardware or they don't have more than one or two TVs, then don't get an XL6 model. There would be no point in that case.
