I thought I posted about Best Buy a couple days back, but not seeing my post. Anyway, they have been a good source lately for high-demand cameras and tech. They don't pile up a huge back-order list on launch day and rather meter them out to their site as they have shipments en-route to their distribution centers. So if you watch their site regularly or other stock tracker sites you might be able to snipe a Studio Display. Or if you physically go into a Best Buy store, a salesperson can usually order one for you even if it shows out of stock on the web. I did this with a Nikon Z9 and had it in 2 weeks form ordering while everyone who ordered later than noon on launch day at B&H is still waiting...
My Studio Display with VESA mount I ordered on March 8 thru Apple has been "preparing for shipment" for a week now. So I don't think they have really shipped out many (or any?) of the VESA mount ones yet. Standard glass for mine...
