I know I do this a lot but here are dates for official PlayBook updates we have received since its official launch. I'm just posting it to give a better idea of when they usually release.
You can see they always come on weekdays around Monday or Tuesday. Also, they're usually within a months span. I would say to look for it Mon/Tues of this coming week but that's just a guess.
i think you forgot an update, cause we got one on a saturday night, the one that addressed the flash security update. i remember everyone was surprised and impressed that rim would push an update over the weekend and not just wait till monday. i could be wrong tho. lol
