Obviously, I have not been keeping up with all the development of the ongoing New Voyages/Phase II series, but the last I had read, Cawley stated his production staff had considered the Phase II engines, but there was some "resistance" (from whom I don't know), so the plan was seemingly abandoned. Obviously, the clip shows the 1977-78 type nacelles, so plans apparently changed yet again.
Can anyone provide a bit of information about this? Did I simply misread what Cawley had to say a while ago? Did someone put words in his mouth he never really spoke? (I will admit I'l miss my Jefferies styled twirling nacelle domes. When I first saw those Mike Minor paintings from the latter 70s showing the radicaly new nacelle structure, I thought, "Hey! Who slapped Klingon engines onto the Enterprise?!"
