Which DNA update will arrive first?

With the calendar flip to September, we've entered the time of the year when Ancestry traditionally begins to release its update to AncestryDNA ethnicity estimates (now called Ancestral Regions). Last year's update appeared for me on 2 October 2023. The 2022 update arrived in mid-August, so this year's could certainly arrive any day now.

Earlier this summer, MyHeritage promoted its own DNA ethnicity estimate update. This still has not arrived for me, and I wonder which will arrive first, the update to AncestryDNA or MyHeritage. Maybe both will be appearing soon, and I'll follow-up with another post or two comparing the new results with the prior versions on the tests I administer.
