There are so many ways to confront this kind of situation that it almost blows the mind. Arbitrary and capricious retrospective dates such as the 2007 cutoff date are highly disfavored - even in administrative regulations. I tend to not subscribe to the kind of 'the-sky-is-falling' mentality that these videos show. I mean, what's new about it being harder for a boutique brand to get products to market as opposed to the big conglomerates? The regulations do indeed suck because they add a layer of expense and bureaucracy that was not previously there. But I am skeptical in thinking that the FDA will disallow a new Nicaraguan puro that has the same ingredient list (i.e., tobacco) that already existing Nicaraguan puros (pre 2007) have. They can mandate the same warnings on packaging but barring the same product type can raise interstate commerce / monopoly / lots of other issues. The flavored cigar guys are likely in trouble though. That stuff is going to get hit high and hard.
Do the regulations mean fewer new blends? Possibly. Are the flavored products (hookah, Swisher, Acid, pipe tobacco) going to have a hard time? Yes, there are lots of questions about what will be allowed in that realm. Does it mean the end of availability of great cigars? In my humble opinion, no.
