Where does teh hype for the Vesta come from anyway? To me it looks like a well made fanship.
Is there an obscure corner of Trek lore that I have missed?
Anyway, it looks so much like the existing star cruiser designs, that it would be non practical to introduce it as anything other then a variant, either a simple skin or the inevitable +1 refit, which would step a bit on the toes of the new Odyssey, after the Odyssey just stepped on the toes of the starcruisers...
The Vesta ordinates from the Destiny
Novels, which introduces the USS Aventine
commanded by Ezri Dax. It's Starfleet's first starship designed around the Quantum Sliptream Drive.
His other ships have also been featured in the Novels or Calendars. For example the Meridian-class USS Planck
appears in the new Star Trek: Voyager novels and first appeared in the Ships of the line calendar.
