Will HHH, Shawn Michaels, Stone Cold, The Rock or the Undertaker will be at WWE Money in the Bank ppv?

On May 19, 2011, I brought my WWE ticket to Money in the Bank for 07/17/11. Before I buy my air plane ticket, I'm just wondering will MITB pay per view will be worth me going to and paying $200 air fare round trip plus $268.15 to stay near the arena in Rosemont from 07/15/11-07/18/11.
