Is segwit2x really called off?
Well it's not sure whether it's completely off the table, but they have indeed called it off for now: 

"Segwit2x hardfork has been called off! Common sense prevails"

You can see some things in this article: https://www.coindesk.com/relief-disbelief-bitcoin-reacts-sudden-2x-suspension/

And this is the message they sent out: https://lists.linuxfoundation.org/pipermail/bitcoin-segwit2x/2017-November/000685.html

Cheers,
