Also, I'd like to throw in my 2 cents on the "Kelvin-prise" vs the "JJ-prise". The JJPrise is, obviously, a technological response to the changes to the timeline. The Kelvin-prise, on the other hand, is more like what a prototype Constitution might have looked like around the Kelvin's time frame. Perhaps the Constitution herself once looked similar. After all, the Kelvin is a really good technological progression between the NX-01 and the 1701, no matter which time-line.
