There's a number of moving parts to the regulations, the grandfather date and the need for pre-market approval. One of the things that people have overlooked is that there's a generous amount of time for companies to either come into compliance or make as much money as they can and then exit the industry. Manufacturer's have 24 months to start the compliance process and then have an additional 36 months to complete the required steps needed to become cGMP. There's also a good chance the FDA will amend the grandfather date if there's enough traction or the regulations will be tied up in lawsuits for a long time. tl;dr: there is still hope!
Shameless self-promotion: if you're a manufacturer, distributor, or knows someone who falls into those categories, we make a software that will help you come into compliance with these new regulations.
