Segwit2x is going to happen. There is no problem on that. Big blockers have their BCH but another big part of Free miners are already locked in to segwit2x.
Don't worry everything is going to be good
Locked in where? Where's the thoroughly vetted software to lock in with?
Signalling means sod all. The only things that counts is allocating actual mining grunt. I haven't seen any statements about that from anyone. There are people still signalling proposals that have been dead for years.
