Over 90% of Bitcoin miners signalling their intent to go with NYA

So BIP91 is locked in with over 95% of users signalling BIP91 which means Bitcoin will block all non SegWit blocks. But over 91% are adding the letters NYA to their blocks showing their intent to run with the New York Agreement software (SegWit2x) which means by the 1st november the blocksize should increase in size but with a unanimous no from the bitcoin core developers in adopting SegWit2x come november their could be a split in the coin between BTC core remaining with the smaller block size and BTC1 running the bigger blocksize.

How will this play out, who knows right now but if Bitcoin splits were going to see a huge reduction in market value with two seperate coins with a shared history. It feels a little like a hostile take over of bitcoin by the developers of SegWit2x.
