F&B is not being DCed. The only retweaking I can think of was the rumour that went around a while back that the forumla has been adjusted to prevent the contents from splitting and going rancid as quickly.
Depending on where you are, certain shades are unavailable in some markets (Australia doesn't have N1 and N2, for example). Or you may have encountered someone who thought you were after F&B as part of the consumer line, in which case they're partially right - the last time I can remember anything F&B related being in a consumer colour story was the gold and bronze liquid luminisers for Hooked.
