That is definitely the Equinox. And the Reliant also looks really good. No blue bussards. I am now wondering if the Enterprises are from the aborted first run from a year ago and they didn't want to waste the money to retool them. All these others are likely more recent and, ergo, more accurate.
Probably true on not wanting to retool (not really fair to say the first run was "aborted" though, unless you think it was always intended to be limited to a small area of England!). It wasn't just the sculpt though - having seen it in person now, the flat grey paint is pretty ugly. If they were going for a solid colour without "aztec pattens", they needed to break out the pearlescent paints for the TMP ship.
The interesting part of this, I suppose, is that the Enterprise-A was on the provisional list of ships separately. I suppose we'll really see their commitment to accuracy when they get there - will they sculpt anew for more accuracy, or just repaint the issue 2 model?
