I'm well aware, perhaps you misunderstood me.
Releasing Beta 7 today would create a waiting period of at least 3 weeks until the GM. This is going against the grain of Apple's ever-shrinking Beta interval that started at 2 weeks and has been accelerated to faster intervals ever since.
Especially since we just saw Beta 6 not even a week ago, I'd expect Beta 7 for next week.
Unless Apple is unveiling iOS 7 or releasing it to the public earlier than 9/10, or is artificially delaying the GM's release by a few weeks, it seems they are "rushing" beta's for no reason.
There has been times in the past where there would be 3 - 4 weeks between each beta. Apple doesn't have a set release, they make releases when they are ready or need too because of some big bug. They could release 7 next few days, or they maybe done with releasing betas to us.
