Console players have a roundabout way of securing one of the newer 26th century dreadnought ships by purchasing one (or many more) R&D packs from the game store. In addition to giving players crafting materials, these packs have a chance of dropping a Universe-class starship, (Federation), a Durgath Temporal Heavy Dreadnought battlecruiser (Klingon), or a Valkis Temporal Heavy Dreadnought warbird (Romulan).
The console edition got a small patch yesterday that liberated captains who found themselves marooned on Nimbus.
