Coinbase didn't sign the notice calling off segwit2x[0] even tho they were an NYA signatory - but rather said they were "monitoring"[1] the situation
I sense some uncertainty from Coinbase on what they want to do next.
edit: also interesting that the price for segwit2x futures has increased today to ~$380 after a low of $198[2]
