I thought there were some reports here recently about several juice manufacturers filing. May be my imagination but I seem to recall some had put that on their home pages.
For a while I had thought one company was planning to file, and was making purchases from them based on that assumption and encouraging others to do the same just to be supportive of that goal, but later found it to be untrue and that there was no financial ability to file in any event.
So it's up in the air; if anyone had already filed it would be all over in ecigarette news, but I don't put it past some companies to make people think they are planning something they aren't now either just to boost sales, however temporarily.
