There was a pretty elegant post on how Python's coroutines can replace callback hell with almost-synchronous-looking async code on HN the other day: https://news.ycombinator.com/item?id=10220712

Wonder if something similar will catch on in the node ecosystem?

Yeah ES7 has async and await which are pretty similar to that

Everyone forgets that Gevent has been around for years, and lets you write completely synchronous looking async code.

I think a better way of looking at it is there isn't enough "cross pollination" in big open-source frameworks and languages.

promises, async functions and generators will make writing async code look more sync in javascript/node.

Whether or not this is a good thing or not, I'm undecided.
