GP Premium Beta Version: 1.12.0-rc.1 is now available. This version brought back Elementor themes that was previously removed from the 1.11.3.
While you may find some themes missing, rest assured that the developers are checking/testing these missing themes for bugs and putting them back on one by one so it’ll have no issues on 1.12.0 official release.
As for the official release date, assuming all goes well, the target is around September 29th for GP Premium 1.12.0 along with a beta release candidate for GeneratePress 3.0.
