At the current block-rate of 7.23 blocks/hour (average over the last 7 days), the fork will happen approximately 420 hours from now (or 17 1/2 days from now).
The Current Estimated Date of Segwit2x Is: 12 November 2017 around 5 A.M.
The block rate is always changing so a more accurate time would be between 14 to 20 days from now or:
Between 8 November 2017 and 14 November 2017
The blockrate varies with the difficulty of the BTC chain and the BCH chain because they share hash-power. Additional forks will add more variability to the blockrate of BTC. I’ll be updating this post as we get closer to block 494,784.
