From Holly "Windstalker" Longdale on the EQ2 Forums:
Sorry we haven't been more specific. We will do a stability pass in the morning and open when it is stable. We are aiming before noon PDT and we will keep you updated.
So wait a minute... Every other beta, there have been e-mail signups a month prior for us to all sign NDA and all that jazz. I guess we'll know in a couple of hours what path they choose to go.
Normally I'd be banging the drum about Public Beta being cool, but hory shet I've got plenty of stuff on my plate with SOE Live videos (11 hours), and various articles before I can even get started screenshotting and previewing Chains of Eternity.
