TJ, you just looped backward about 2-3 days. Reread the SEC rules and regs re: blank check companies. They DO NOT have to file anything until there is a material change in the company that would cause them to move out of shell status into rev gen status. An 8-K is NOT required unless and until the merger is complete, then, it must be done within 4 days.
If the merger fell through or is on hold, they still are in shell status and NOTHING is required.
Sorry, but I already posted the rules. Go through my archives if you feel so inclined.
