Before 1 January 2050, will any human cryonically preserved for at least 1 year be successfully revived?
As of 2014, around 250 legally dead people in the United States were in cryonic preservation. At least 1,500 people around the world have active plans to join them in cryopreservation in an attempt to thwart (or at least delay) permanent death by freezing (or more technically 'vitrifying') their corpses after their legal death. Many of these 'cryopatients' have had their whole bodies preserved; others have opted to have only a cheaper neuropreservation. You can probably guess what that means. For more information on the current state of the art in cryonics, you can visit Alcor's website, which is one of the most prominent organisations in the field.
This question asks: will any 'patients' who have been in cryonic preservation for at least one full year before 2050 be successfully revived before 1 January 2050?
For the purposes of this question, a revived patient must be determined by at least three recognized medical experts (M.D. or PhD in Biology, Neuroscience or equivalent level of education), each of whom is independent of the cryonics organisation responsible for the patient, to be conscious, alert and responsive to questions for at least 24 hours at some point within a year and a day after midnight on the date that the attempt to revive them is made.

Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats
Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
