One nice aspect to CGI-ing the effects would be the loss of the frequently ugly 2 and 4ft models. And I can't say I would miss some of those really lame shots from S1. And maybe even make the D to scale with planets finally.
I just hope that the modeler(s) are people who appreciate the material. Go for the look of the 6 footer. That model in Enterprise's last episode was not quite there, at least partially due to the usual CGI lighting problems.
