Its the 21st sod do you honestly feel the current beta3 build is close to being released, regardless of what has been said.
We are still seeing bugs reported (though not many serious issues), personally I would have though another beta build to confirm that previous bugs reported have been squashed.
I honestly don't care when it is released, only that when released it is fit for purpose, there are areas that aren't fully working yet. Much of that may be to do with having the back ground infrastructure up and running, so that streaming updates, clouds services, web file reputation analysis, etc.
