Fact: A ship with the basic Constitution-class saucer-hull-nacelles configuration can be seen in the trailers. Another ship fitting that basic description is seen in the comics.
Speculation: They are of the same type, presumably a forerunner of the Constitution-class.
On the other hand, starships of that configuration are not at all rare in Trek stories set in the mid-23rd century. It's been the default configuration for Starfleet vessels for as long as Star Trek
has existed. So the similarity doesn't prove they're the same ship, any more than you can prove that two blurry photographs are of the same person because they both have two arms and two legs.
