Definitely will be in the release - it is currently in the proposed channel. It is waiting for Canonical to complete the migration steps of GNOME-Shell & Mutter before it will be allowed into the release pocket (i.e. budgie-desktop has a dependency of mutter … and gnome-shell separately has a dependency of mutter)
budgie-control-center v1.0.0 as of today migrated to the release pocket.
