The Excesior?? Isnt that, like, 30 years early in-universe?
No, I think the collector series probably includes ships from multiple eras of Trek. Since two of the ships mentioned in that sentence are separately specified as being from the new 2013 movie, that probably means the Excelsior, which doesn't get that specification, is not from the new movie but is the familiar one from ST III/VI.
That's how I interpreted it too.
