It's good to be skeptical in this situation. I have been the whole time. However, just because it hasn't happened lately doesn't mean it won't happen. What gives me hope is the BOD took shares as a bonus and they signed an LOI already.
I don't know if it's happened in the last 5 years, but the better question would be.. how many of those revoked companies have actually filed the form 10 with two years of audited financials to get re-registered. Since I'm familiar with most of the stocks on your list, I would say most of them aren't even around to do that! HA
