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.
in all fairness, the actual code changes from core 0.14 to btc1 are minimal. there's been ample time for auditing/testing. the problem with the timeline was always that 3 months is too short for compatibility breaking forks in bitcoin. and of course, the fact that there is not widespread agreement among the community to hard fork.
at the end of the day, all we can do is wait and see. there's not much point speculating about what miners may or may not do. and if we're being honest, bitmain alone can determine whether a major split occurs or not. and they are holding their cards close. we know that BCH is their baby. what we don't know is their long term plan here.
