100% correct. First off as someone who uses the HoloLens daily FOV becomes less and less of an issue. People have to realize with FOV that it's a happy medium, most tech is about compromise and they did a great job with the hololens. Let's say they decided to add a wider FOV, they would have to add more glass, more processing power, longer battery life, more R&D, all of these things add up to a greater price, a heavier system and later release date. It's about equalibrium.
