More US shows?

Think there will be more US shows(hopefully Detroit...) announced for this upcoming tour or should I try to get to the one of the already announced shows?

I was in the same position as you were about the Chicago show. I'm from WI and I know that Bon jovi usually goes to Wi. But, they have already been here 2x's for the tour so I decided and not to gamble and just get the Chicago seats. If they announce Madison, I guess I'll just have to sell the tickets I already got.
