The beta release was 10 months ago . In December, it was announced that 3 more weeks were needed . I suspect there has been a lot of unanticipated work needed. However, the latest commit to the K2 v3 dev build was over 2 months ago.

Can we get an update to the current status of this project and realistic timeline?

No answer there, just more runaround...

So, the official launch date is 2015-08-01?

The event is 4 - 6 / 9.

OK, I see 4-6 September: joomladaybrasil.org/2015/

Together with Lefteris Kavadas (backend guru) and Krikor Boghossian (frontend guru), K2 v3 development has re-ignited and is on a steady track for a realistic release date by late April 2016...Within a month's time, we'll make every effort to finalize all remaining issues and release K2 v3 :)
