its going to be interesting to see how the network reacts to segwit being released...
i wonder how much effort it will take to get that 95% they want
I don't think it was specifically stated (yet?) that it would be at 95%. People only assume this as it was used in the past.
Much of the support for Classic will just accept segwit size increase and continue lobbying for another one.
This is one of the problems with increasing the block size, people (due to lack of knowledge) are going to continue cheering for another increase pretty soon even if that one would effectively cause huge problems. Just because we can do it now (after segwit), it doesn't mean that we will be able to do it once again next year. I'm certain that one or multiple developers have talked about this.
