It's not going to be in Miami every year, only in 2010 because the Super Bowl is also there in 2010 and they're testing the idea of having the Pro Bowl the week
before the Super Bowl.
Reading the article, it would seem your Hawaii Pro Bowl isn't entirely in jeopardy. I can't ever see the Super Bowl in Hawaii every year, but if a new stadium was built there, and the NFL continues to have the Pro Bowl and Super Bowl in the same city, logic would dictate it would have to end up there at least occasionally.
This experiment could actually really help your Hawaii Pro Bowl weeks because no one I know cares about the Pro Bowl. I travel to several sporting events a year and my friends and I have never even
yawned the Pro Bowl. If they can move it around and create some interest, perhaps when it goes back to Hawaii more people will be interested in attending.
