The last few times they tried banning 80%s it failed because they either didn't understand federal gun law or they accidentally (?) made it an illegal taking. Eventually, they are going to figure out what works and pass something, IMHO.
I have heard from at least one person in the MGA that this year is also different because Frosh will be directly championing the bill, and it won't be introduced/managed by Del. Lopez as it has been in years past. I believe Speaker Jones will introduce it and it is expected to be a priority for passage this year, moreso than in years prior.
In addition, because the AG is driving it, the expectation is that it will be more focused on punishment and penalty than on establishing what constitutes "legitimate homebuilding".
