The spaceships have all been shot on film, and they are of excellent quality, as the above image shows. So if they redo all the VFX with crappy CGI, I won't buy it. The CGI in TOS-R was an enhancement over the blurry and noisy VFX. But CGI certainly won't be an enhancement over the TNG effects.
You don't get it...as many still have not...the CGI was understated to LOOK like it may have originated out of the 1960s, except executed with computers. It was not meant to look like crisp, state-of-the-art ST:Enterpise FX. STNG would have FX appropriate to the "modern age". They would most likely even have higher detail than Enterprise.
Ugh, please don't get me started on ST: Enterprise CGI...
