That is strange. One I ordered at 5AM PT is arriving after one I can order now. I think this is because local stores will have it in stock and that stock can be used for deliveries.
This discussion has completely lost the plot if we're now pointing delivery has moved forward....a day. Mine was also 1-8 from the start.
Guys, these times will improve. Apple has covered their backs based on China, covid, lockdowns, delays and other issues - it's all to be expected with BTO. I'm expecting mine before end of July.
