The $200 change fee is the same whether you cancel now or a day before the flight, so as long as you remember to cancel it, there's no downside to waiting.
Your other hope is that there is a weather delay that day and they bring in a travel waiver. Either way, there is no benefit to changing before the day of flight unless you have a new ticket you want to apply the value towards.
