I ordered just after midnight and all phoens were showing 7-10 days.
I'd like the dates to be conservative but I fear that Apple, a company renowned for having a high degree of control over its supply chain, will already have allocated upcoming stock to its markets for the next few weeks and so this date is likely to be based on the UK arrival date of a specific shipment. Any shipments leaving China over the next couple of days are likely to be prioritised to the US & other large markets.
We might be lucky and get our phones before the weekend of the 5th/6th but I think it unlikely we will see any movement in the dates before next weekend.
I do of course hope that Apple prove me wrong!
POSTSCRIPT - I think Apple may regret what they did with online orders when it comes to next year's release. After all, will anyone even bother trying to go online? I know this year's debacle is a function of the lack of pre-orders but we know now that customers ordering online at Apple are at the very bottom of their list of priorities.
