Highly doubtful. The only reason to suspend a pink sheet stock is for fraud or a significant event/confusion. For example, GM stock was suspended for about 20 minutes do to people thinking commons were coming out of BK okay. Once the company rectified this statement, it began trading again. Even then, it is very rare. When cancellation was announced it still traded for several days.
There are Q's that trade for years on end until resolution. If commons are cancelled, we will here about days before that actually happens.
There has to be an event or reason for suspension. Niether Indy Mac, Lehman or any of the other Q stocks have been suspended until resolution happens. Nice scare tactic though...
