Look, on one hand I can see what you're saying. On the other hand, I'm wondering just how much is hype talk. Have you actually sat down with Unity and developed a full game? I'm not talking about a teeny graphical test game. I'm talking about a large game which pushes all of the areas you're trying to sell Unity to everyone on- fallbacks, pipelines, etc. Things can look all dreamy on paper, but full-on game development is a minefield of difficulties which often require as much flexibility as possible.
