I think the 7 day rule only applied to the earliest pre-orders. All current orders are queued by date of payment. I don't think your order is even in the queue until you pay.
mm, i think probably i'll cancel the order
i was struggling because i didn't placed the order early but this make my choice easy
i will evaluate a purchase when they will release the new miners, having a clear frame about shipping time behaviour and how things will evolve
The difficulty increase slows as it grows, think of it this way, for the difficulty to double from the point it's at now, all the asics that are in the wild right now will need to double (plus more to cover the gpus and fpgas) that's a lot of asics. So basically, the difference between getting it week 1 vs week 6, really isn't going to make that big a difference, nothing like week 1 vs week 6 for the avalon batch 1.
BFL just announced they plan on being caught up by late september, so if you ordered in May, June, you might get it by September, KNC? October. So pay up, get with the new world order of ASICS, it's awesome over here ;-)
