Listen, Bioware is in the same danged if they do, danged if they don't position that all companies find when they release a new MMO. They can't please everyone. Either they have a mass release where the servers crash all the time and have hella queues (WoW), or they stagger the entrances of the bulk of their players so when the game is officially released the hit will not be as bad.
If they attempt to target a time/date when everyone gets access and don't follow through, the whining would be worse than it is now. As for communication, would you rather have them babysitting their email system, sending out bulk emails or monitoring the servers? I vote servers, I don't need any email other than the one saying I can play. If that comes tomorrow, I'm happy. If not, I'm still happy to get in when I get in. I have friends playing now who are getting ahead of me, big deal. I'll catch up to them eventually.
