Cryonics has recently attracted a small but dedicated opposition who've adopted the framing that cryonics is a scam which consumers need protection from. (I won't link to them, but you can find them in any google search for the word "cryonics".) The basic issue seems to be that it matches their perception of a Scientology-like cult. They've been growing more active, so I wouldn't put it past them to try to push something through this year.

There was a bill specifically targeting cryonics proposed in 2004 in Arizona. Arguably the Ted Williams event was its cause, so as long as cryonics organizations are more careful to establish clear evidence of consent in celebrity cases, the likelihood of it being repeated in a given year should be relatively low.

Oddly enough the publicity from the Ted Williams case triggered an investigation in Michigan in which they determined that CI was an unlicensed cemetery. While not exactly a new law, it is certainly new legal restriction as the existing law for cemeteries prohibits preparing the body on site.

That's not to say there aren't useful features of cemetery law -- e.g. there's a law for making sure that 15% of a cemetery's monies are kept in perpetual care fund. A law like this would make sense in the context of cryonics facilities if they were considered as a separate sort of entity from cemeteries that is permitted to do things necessary for patient care which have no relevance to a cemetery situation, such as preparing the patient on site.
