How long do you think the Rox wil wait till they start looking at other options? Do you think they have trades ready in mind just in case they have to go to plan B? I think (but not agree) that the Rox will wait this out till the last day. They have been jumping through hoops for Ming since day one, I don't see it stoping till they have no other choice.
I assume they already have some contigency trades worked out and, if all else fails, an alternate #1. They said they couldn't wait till the last second, and I'm sure they'd prefer not to, but I think they probably can and would if forced to.
