To give some perspective to "VERY soon".
Full builds take a long time (as in multiple days). And also uploading all these packages to mirrors takes a considerable amount of time.
My past experience is that if the 13.1 pkg builders start at September 1th the pkg might be available around September 7th.

NB: I'm not part of the pkg builders team, so I'm not aware of the specific plans and dates. Just my empirical 2 cents on this.
