The 2009 Enterprise made internal sense, because it was designed and built by different people in a different time with different goals in mind. This Enterprise, if that's what this, is the same ship that Pike commanded three years prior and Kirk will command in 8 years.
I have to figure out why they did such a massive refit and then a retrofit of the ship back to what it was. Everyone says it's not a reboot, and I've been pretty okay with that, easily explaining away most "supposed issues" like Michael and spore drives and even cloaking and Klingons with my own head canon ideas. But a massive change to the Big E would be too much, especially for a show that, despite popular belief, does a pretty good job in referencing and paying homage to all the Star Trek that has come before it.
I mean, here's hoping that it's the USS Farragut, or the ISS Enterprise, or a more accurate Enterprise that passes the dark room squint test.
