Sorry, folks... this:
is NOT the Enterprise from Star Trek XI.
It was created by Gabriel Koerner, a professional CGI artist who works in the industry way back in May 2007.
This particular CGI model of the Enterprise has appeared online before but from different angles, with the usual speculation that it might be the J.J. Abrams version of the ship. Personally, I think that is just a testament to Gabriel's talent.
Although it is quite different in many details and I'm a hardcore classic Star Trek fan, I have to say that I would be ok with this as the new NCC-1701.
If you want to see what it might look like in motion, look no further... here is an animation that he created back in May using his CGI model:
I think it rocks and it has me more curious than ever regarding what Abrams and company are going to come up with for a new look.
I guess we'll find out in about a month when the trailer hits. :-)
