long time to go by now. given the update speed for this game in terms of content additions is really slow i wouldnt wait for the full release. plus there is no real reason to start over with a biome addition. the gamemap is designed that you can keep playing it aslong as you dont fully explore the entire map for no good reason as you can find all you ever need by just going in 1 direction towards the edge that isnt directly north or south.

also anyone who beliefs SONs will go gold in 6-8 months given all the shortcomeings and issues of that game currently needs to seriously reconsider trusting these devs.
