Well, with all these amendments and supplements to the plan, I still don't see anything of value for commons. But it's all up to the Judge. So I agree with level42 it's 50/50.
Interestingly enough, just watch, if the plan is Approved the stock will climb somewhat after the ruling... Probably because of shareholders hearing a positive word "Approved" and not knowing what that means for them.
I've seen stock climb 100s% after approval. Just remember your shares could wipe out as soon as the next day. It's usually a week or 2, but I wouldn't risk that. The stock just stops trading at some random time during some random day.
If the plan is NOT approved, then the bankruptcy process starts all over again. That's why I think it's more likely the Judge will approve the plan.
