There absolutely no hope right now. The idea (for better or worse) is that there will be some scientific breakthrough in the future (e.g., nano-scale medical robots) that will make it possible to repair the damage done by the current, very crude, freezing technology. You're taking a gamble on future technology. My impression is that the typical person signing up for cryonics thinks that there's a small chance of success, but almost no downside if it fails (you're already dead).
