I would wait. I had 3 flights for this week and 2 got cancelled and 1 got changed. I got refunds on all of them but I had to wait until about a week before the flight for them to tell me about the cancellations and the flight time change refund info came about a week before too. They are unsurprisingly pushing the vouchers until the last minute.
