so yeah, a wipe someday, whenever it gets released, but re-reading your post...That would mean you could play years and then be wiped, which seemed to be your concern.
May I suggest you try it out, play it. It may never be "officialy released" and if it is, you may lose your tria and expereince, but you will then know the game and your character and be a part of the community.
Of course you MIGHT not want to spend 20 hours a week into leveling your character up, because that might be hard to take. But I did, and it was fun. Ready to do it again, someday.
Hope that helps and is relevant enough.
