In other Beta sites that I've been involved with, the Beta badges are normally given at the end of the private Beta period.
Since things are beginning to change in the Area 51 process, and the extension of the duration of the private Beta period may have been indicative of this, is the Beta badge going to be awarded on a different schedule now?
(the temptation is to ask if the criteria to earn the badge have changed, but that appears to still be under wraps for the 2.0 sites the last time I looked into it)
