If they pull out today, we'd likely fold tomorrow. Wages are due and there would be no-one to pay them.
They aren't in an exclusivity period any more, there's nothing to stop someone else making an offer. Surely if others are keen, they'd be slamming money on the table as quickly as their hands could move?
Lastly, as others have said, if Pinnacle have got cold feet they'd have pulled out by now. They wouldn't be racking up more bills going backwards and forwards with the FL.
