The biggest problem for me with visual languages:
How do you talk about them? How do you write about them?
It may well be solvable - I'd like it to be, I spent a couple of years of my spare time toying with visual languages, and I still think as an idea there is a lot of potential. But you need a notation that can be read out in a way that makes semantic sense, the way mathematical notation (despite my very many reservations about mathematical notations) can. And mathematical notation is a good example of all the problems it brings in terms of tool support to even ensure you can reliably typeset it without having to include images of it.
I think it's more likely that we'll see improved interfaces to decorate or explore a textual code-base better, though, possibly with some languages starting to be designed with such tools and representations in mind if/when we start to see something closer to a standard emerge.
