First I voted yes, but now I've revoted for no.
Of course I'd like to get more content into the game, even I had to wait half year more to release. But it cannot affect quality of content previously set.
If you have extra money, I would prefer to record voice dialogues instead of wilderness areas. The game is huge, and you won't be able to record even 1/5 of all dialogues, but even that it will add something special to the game.
