How Pre-order list? Release date S19 XP 140Th?

Hello dear community and support. I'm looking for the pre-order list and the date when I can buy an S19XP ASIC miner (140Th). Is there a way to sign up for the newsletter for the next batch? Unfortunately, there is no information about this on the Bitmain website or I can't find any information on the website, and the support has not given me an answer to my email so far (6 days). Best regards
