Around 3000pcs at this time connected and my and many others miners are in still in packages on its way.
Not sure where do you see 3000pcs. I can see about 1.4K at the moment. Though, this grew rapidly since morning while it was few hundreds only. So I assume it's all relatively fair play by Bitmain so far.
Though, I am not sure if Antpool is working, so I've no idea why there are still around 900 asics on it...
Antpool 1.96MHs - you can see it at this link
http://miningpoolstats.stream/bytom1 960 000h/s / 780h/s = 2512 machines,
uupool 0.49Mhs
490 000 / 780 = 628 machines.
Total: 3140 machines.
