First of all, I agree with @davis196, there's still a long time until the next halving and too many things can happen.
However, I do expect wider acceptance, more companies do business related to bitcoin, increased popularity and number of users, but none of that is related to halving. This happens pretty much with every day passing.

What I expect more? On long terma I expect LN get used at a really large scale, I expect more similar solutions emerge, I expect we get to the point Bitcoin gets as easy to use as the fiat credit cards and that also get implemented in shops (eg. grocery store chains), I expect large businesses enter into mining either to burn excess energy, either to keep the network secure for the sake of their own musiness.
How much of this is going to happen until the next halving I don't know, but one can hope.
