Impressive result indeed. I can see this as a logical extension of work done in the '90s where crayfish brains were plasticised, sliced then imaged under electron microscopes, giving a 3D dataset of the brain structure. Nowhere near as detailed as this, though.
Next step is to calculate the complexity of the drosophila brain. I did that a few years back for the C. Elegans brain - although I doubt my algorithms will be up to snuff, as they tend to be combinatorially complex - but who knows, I might get lucky.
