The thing SE can do to silence the critics? Get their userbase back over 200,000(atleast) users and keep it there for a few years. Anything less than that is a total failure. I dont see them getting anywhere close to that number before PS3 release and depending on how good the upcoming content/UI changes/job changes/Auction house addition shape up I dont think they will keep that ammount of subscribers for any signifigant period of time.
