I wonder if they’re going to be selling models pre-packaged with bands again, which is why they haven’t updated the Studio.Educated guess: the stock ready to ship on Oct 15 will be super limited or non-existent. Delivery times will be many weeks or even multiple months for most models from the beginning.
So Apple sees no benefit in offering more details like specs, models, configurator etc. before preorders start. No need to build a hype. There will either way be more people wanting to preorder on the 8th than they can serve over coming weeks no matter what.
