i for one would not go along with such a fork. i think many others would agree with me. So long as there are atleast a few other people who agree, a hard fork will not be possible.
This change is (eventually) such a critical and needed change, if we want Bitcoin to be used for small payments as well, that it will simply be done. Anyone who disagrees will form their own payment network.
The alternative scenario is that for some reason the dev team doesn't have the will to do this, and users eventually start to flock to other cryptocurrencies.
