While I would love them to license one of the 2 beautiful CGI models already created
and one of them being from ILM for 1994's 'Generations' and the other for ENT "These Are the Voyages...". But most likely CBS Digital would start from scratch and build a new CGI model. [frowns].
There are two different Lightwave CG models of the Enterprise-D used in canon already. Why doesn't Paramount/CBS ever license CG models?!
FX houses probably wouldn't use them anyway, since Paramount/CBS would probably make them pay some kind of licensing fee, which would cut the money they're getting for remastering the show, and using someone else's model doesn't give them the amount of control they could get if they built it themself.
