My understanding was that it was, at least at this point, an information gathering session rather than a move to actually do any banning of ownership. That said, it was started from a massive quantity of misinformation, and it certainly seemed as though the people behind that misinformation were operating with the end goal of a ban. As to what species or genera would be banned, I think the main focus was on large species like Burmese and Reticulated Pythons, along with Anacondas and possibly large boas, though so many people have BCCs and BCIs that I think they might be unfeasible to ban. The whole thing stemmed from a faulty study which concluded that the Burmese in the Everglades could eventually spread across a lot of the southern USA.
If the people on the committee doing the deciding are rational have accurate information, it won't go through, at least not based on the idea that burms could spread across the country, which is plainly false. Frankly, I don't see how rainbow boas could be affected by this unless there's a ban on all snake ownership - they're relatively small and therefore not a threat to humans, and their environmental requirements would not allow them to survive in the wild in the vast majority of this country. They just aren't a problem.
The ball python people are justifiably worried about it though, because ball pythons are in the same genus as burms and retics, and if there is a move to ban the genus, rather than just the large species from it, they'd get screwed. The whole idea is that they'd get defined as injurious species under the Lacey act, which would prevent interstate sales and transport for anything other than zoos and other legitimate scientific purposes.
Anyway, back when all the fuss happened with this in April, it was just an information gathering session, and having heard nothing about it since, I'm operating under the idea that in another 6 months to a year when I'm in a situation where I'll be financially and space-wise able to get a BRB that it will still be legal to do so. Here's hoping, anyway.
