IMGGorBust,
Regrettabley, the FDA can "restart the clock" if they deem it necessary. Regardless of fast track or not, FDA has the right to say they need to re-review in lieu of new info that is brought forward due to fast track communications.
I would hope and expect Dean and Co. to make an announcement if this were the case.
Bottom line, the FDA can take longer than 90 days if needed.
This is why I keep saying that this is a FDA, period. When they say yay or nay is when things will become interesting. Until that time, we are going to see manipulation at it's finest. It's a shame that's how the game is played.
There is no countdown clock, just ignition or explosion.
