Its not the merits of core vs 2x thread. As i said in OP, I am curious as to how this might play out. When will we know how many are "locked in" to either side? Will the fork happen regardless and we wont know until after how many miners support each or is it possible that the fork will not happen due to overwhelming support for either side?
TBH I don't know and this really requires clarification.
The miners are in opposition to the running nodes at the moment, and the user community is utterly impossible to gauge accurately. Business doesn't seem to care, it will go to whatever is successful.
I believe that ultimate control comes down to miners in the end. If miners mine 2X and nobody mines the legacy, then that's all she wrote.
