I think even these numbers are a little high, except for the fact that you didn't limit it by jurisdiction. Cryonics isn't hot right now, but longevity certainly is. I don't think there is enough attention on cryonics to justify legislation, but even if there were, the first steps of the legal battle would be court decisions rather than legislation.
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...
As we did last year, use this thread to make predictions for the next year and next decade, with probabilities attached when practical.
Happy New Year, Less Wrong!
