You do realize any dates given for anything during the development of a game not just mmos are just WAGs right?
My point is they will update when they know something. Maybe problems integrating or migrating log in info. Who knows. If they responded now more than likely it would be Soon(tm).
I've followed a number of mmos from idea to finished product and have seen two camps when it comes to updates. Those who wait to give an update till things are tied down and set in stone. These are the ones who use soon(tm) the most and are criticized for it. And those who give dates and then have to push them back for various reasons and are criticized for that too.
In short nothing SS does from this point on will please everyone so best bet is to wait and not call out the devs. Since they will release info on their own time table.
