The planned launch of update 2.2 is mid October. That's about 6 weeks till launch. Beta testing usually takes a month. So will we get the beta between September 12 and 18?
Beta most likely 2, maybe 3 weeks. So expect news about it next week most likely. I will guess is development is still actively ongoing, including internal testing, so they just don't know specific date yet. That's why we don't know.
