The current brains are totally lost. Maybe a partial image of memories could be recovered when we understand more about the process but I wouldn't count with it.
But if tomorrow we would found a suitable antifreeze in some obscure creature that is not rejected by the body and does not damage the cells, this is a game changer. To be able to put the body just about to freeze but not further... that would be awesome.
Would be a key to 1-hibernation and long term space travel, 2-increase life expectancy slowing the metabolism and this mean slowing cancer also, 3-increase in the range of temperatures that humans can stand without suffering chill burning and losing fingers.
De-thawing would be still a brutal process. Not all cells would survive.
