I think it's unlikely that we'll have the technology to revive cryopreserved people without also having at least a significant amount of life extension technology. Many of the same kids of human body repair you would need to do to revive a frozen person would be helpful in lengthening lifespan.

If we invent immortality before we invent unsuspension then hopefully the people running the cryo foundation become immortal and continue to care enough to revive their friends and relatives.
