All the funds that were frozen have been returned. There are two types of funds that were not returned:
Some people claim funds of theirs were transferred out well before the freeze. They claim it must have been by the same person who got the account/password list, but before the big attack. They claim these funds have not been returned.
People who profited unfairly during the flash crash had their transactions undone. Some of them claim they are entitled to their profits. (Some people bought thousands of bitcoins at absurdly low rates.)
I think that people in the second category don't deserve to profit from the theft. As for the people in the first category, there are only two people that I know of who claim this and the amounts involved are quite small. So I think the true answer to your question is most probably "yes".
