With current state of game if they release they will have an influx of probably 50,000 players in one month, servers will tank, game will be review bombed on game review sites, and the population will fall to around 5k players probably, that will taper back to a little more than what we have over a 6 month period.
I don't care what the dev's say about how many players they supposedly have. What I care about it what I see. Which is usually the same 20 some people in chat, and then Me, Myself, and I in my area.
Regardless of wipe or no wipe, there is a ton of grind and not a lot of reason for grinding.
