In such respects, it certainly doesn't matter what I or any of the rest of us think. It's strictly determined by what they do. They can wait as long as they want to really. But with all due respect to what the company has stated, I would say sometime between now and Wednesday as well. After all they've got all the info, so why not let the cat out of the bag while things are heating up? :-)
I doubt you'll see one. After seeing the last gold company put out a fake report and get suspended for ten days and then open on the grey sheets, I'm sure they'll be hestitant to make the same mistake.
