IDK that they have the 2 week luxury, especially if 9.2 is meant to fix some iPad Pro launch bugs. They may need to accelerate to 1 week betas go get it released in the next 3-4 weeks.It would probably be tomorrow if we follow the 7-day beta cycle.
But iOS 9.1 beta 2 was 2 weeks from beta 1. We'll wait and see.
Unfortunately more often then than not these claims don't hold up, which makes it that much harder for any real claims to come about and for anyone to put much faith into them if/when they actually do.
