I want it to be the -E with a new captain, but would almost be happy to see -H. That would be funny and ships named Enterprise don't last long. I think a sadder outcome is if you go by the new fleet hull details the individual ships don't get names like modern fighter jets. Maybe they go semi-Andromeda Ascendant and the crews are fully non-sentient holographic/android with only the captain or command staff being people.
