I voted for "no, don't change it" becasue I'm not sure what would be gained by changing it.
That said, I think 3EN (for Third Edition News) has enough in common with EN to hold the line as far as the currently existing brand, while having a bit more meaning to the uninitiated than simply EN.
So I probably should've chosen "would depend on the name", but that seemd to imply that a "really cool name" would be good, whereas I thin this one change might actually be all things to all people.
