I agree. Resuscitation seems unlikely, given that the freezing process itself damages the tissues, as well as the degradation that has already happened post-mortem.
We can debate the degree to which cryoprotectant perfuses the brain outside a laboratory test of tissue, but vitrification appears to preserve the fine structure of tissue very well:
Well, they resuscitated a nematode. That's... actually worth updating my view of how well they can preserve things. I should go ask people for help interpreting that paper.
100 years from now is a long time for medical advancements. Would you imagine having an MRI or CT scan 100 years ago? Or that they'd induce hypothermia in an emergency room to stave off damage from cardiac arrest [1]?

There is evidence of synaptic preservation in preserved and restored nematodes:
