Yes, I’m wrong about this being prisoner’s dilemma. One side defecting (dieing) against other cooperating (cryopreserving) won’t make first side better off and second one worse off.
So it’s just insufficient communication/coordination.
We could also consider a game that was perhaps a step closer to the original. Leave cooperation and defection (and their PD laden connotations) behind and just consider a pair who would sincerely rather die than live on without the other. This is plausible even without trawling Shakespeare for fictional examples. Here on lesswrong I have seen the prospect of living on via cryopreservation without a friend joining them described as ‘extrovert hell’. Then, as you say, a ‘cremation’ equilibrium would be the result of insufficient communication/coordination. A high time and or emotional cost to transitioning preferences would contribute to that kind of undesirable outcome.
Incidentally, if we were to consider pair-cryo selection as an actual PD the most obvious scenario seems to be one in which both parties are overwhelmingly spiteful. Cryopreservation is the defect option. Where life is preferred but it is far more important to ensure that the other dies.
