> I have yet to see a "Visual" programming environment that is even close to as efficient as normal programming. I may well be in a minority on this one, but surely time spent on this would better be spent in other areas like improving C# interoperability etc?

Visual programming languages are not designed for experienced programmers, who would rather type it out. It's designed for those who don't have a programming background, but still might need to wire up some logic on occasion. It's not necessarily meant to be efficient, just user-friendly to someone with no programming experience. If this language makes it easier to write tutorials or get into making games for people coming from an art or design background instead of a programming background, I'm all for it.
