Yes, most have apparently - although I know powdair are getting some stick from a few stragglers in getting refunded, due to the delay from the card payment provider back to the customer depending on which credit card etc... remember its world ticket that are the ones that held all the money - not powdair, and powdair is completely void of any control of the refund process other than give the instruction to refund which their CFO did in early December....
There is also a healthy amount going on for next season that's for sure!
