Has anybody actually spent any money?
The applications is where the cost to manufacturers lies. And yes, that money has already been dished out by many manufacturers who have applications in.
what's left is an actual approval. The FDA hasn't approved anyone yet, but they have a full year to do so, during which time those who have submitted their applications for approval can continue to sell their product legally.
So, now its just a waiting game to see what the FDA will approve.
