Although changed somewhat, Abrams was smart enough to not screw around with the iconic saucer shape on the original NCC-1701. It looks as though he took bits from both the old and new TV versions.
This from Abrams, “If you’re going to do Star Trek there are many things you cannot change. The Enterprise is a visual touchstone for so many people. So if you’re going to do the Enterprise, it better look like the Enterprise, because otherwise, what are you doing?”
The new Star Trek movie follows a young captain and crew of the USS Enterprise. And if you want to see the Enterprise in action this weekend, then go see the new James Bond flick "Quantum of Solace" where the first real trailer will be shown.
