Considering that the DSM IV had different autism subtypes, (Asperger's Syndrome/HFA/PDD-NOS/childhood disintegrative disorder etc.) and we now have the DSM V which groups everything under one label, 'autistic spectrum disorder', I fail to see how autism terms would become more complicated in the future, regardless of the biological causes that might be found for different types.
The trend currently seems to be to simplify and provide an umbrella term, rather than make things more complicated.
The trend is that way because it was too complicated diagnosing them as separate conditions. There were too many people who were difficult to pin point so they just used the umbrella term.
When causation is found for each condition it will be removed from the umbrella and called its separate thing.
This is already happening many things that were called autism / ID in the past are given a new name usually linked to the gene effected.
