I just don't buy the "apple is holding out for silicon Macs" argument, I hope and think the release will be soon, as in by the end of the week. I think the GM is locked for the new devices, and will be released to developers ASAP. If they hold off a GM until after this event, what are all the silicon Macs going to run? Apps that haven't had a chance to be fully optimized for Big Sur? What kind of customer experience is that? Nothing will be ready to run on a silicon Mac. I think that would be a mess, and I don't think they would do that, at least I hope they don't.
