Node.js and io.js will be merging

This Github issue was news in May. If you're looking for a status update there's nothing to see here

I'm stoked they are merging. I think it's not a great idea to rename the project.

Node has had trouble getting traction in some enterprise circles because it was "0.x.x" instead of "1.x.x" or seen as early technology, or JS is not strongly typed, etc etc. But at least it had name recognition.

Nobody outside the community has really heard of iojs. If they go forward with a rename, it's going to appear volatile - if outsiders even realize it's the same project.
