You can get them while everyone is still as green as grass, ironically.

Before it even officially launches, Tabula Rasa already has a Veteran Rewards program ready to roll. From a press release:

As the November 2 release date of Richard Garriott's Tabula Rasa nears, NCsoft today announced a Veteran Rewards program for players of the upcoming sci-fi MMO game. For each increment of three months with an active account*, AFS recruits will unlock exclusive in-game content and items such as emotes, gear, crafting schematics, titles, pets and more. Players will also receive an initial one-month reward that includes access to three exclusive in-game emotes.
