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...
