All Core vs except Luke JR I think which actually wants to make the blocksize smaller, want to eventually make the blocksize higher. Im sure we will sooner or later see a bigger blocksize, but for the time being we should enable segwit, let it run for a while, then eventually go 2MB, specially as more and more people start using LN since they will realize onchain transactions aren't worth it for small payments when you have LN unless you really need to because you are sending a decent amount.
