No, there is no guarantee that they will. However, whether they do or not depends really. For the sake of argument, what if they decide to revive a cryonically frozen person for historical reasons? For example, Benjamin Franklin once stated in a letter that he wished it were possible for him to be preserved and revived in a future century, just so that he could see how America and the world would of changed in the intervening period:

If it were possible to bring back Benjamin Franklin today, who would not want to meet him? I would.
