Ryan Seacrest Tweets: 'Idol' Season 10 Audition Cities and A 'Big Change'
Ryan Seacrest went to Twitter today to announce the audition cities for the tenth season of American Idol -- and then some:

First, the audition cities, some of which were already announced. USA Today filled in the extra details, so if you're planning to be the next Lee Dewyze or Crystal Bowersox, here's where you should be:

Nashville, TN: July 17, Bridgestone Arena
Milwaukee, WI: July 21, Bradley Center
New Orleans, LA: July 26, TBA
East Rutherford, NJ: August 3, IZOD Center
Austin, TX: August 11, Frank Erwin Center
San Francisco, CA: August 19, AT&T Park

These are just the initial stages: whoever goes through these rounds will audition again at a later date, this time in front of the judges. Auditions are, of course, also open on MySpace.

Ryan also hinted at a "big change" which will be announced tomorrow. Any guesses on what that could be?

You probably heard that in the middle of season 9 Idol producers launched a pretty big online survey, asking viewers on their thoughts on the show, the judges and the format of the competition. You can say that the change Ryan's hinting at involves a massive tweak in the rules. (If that's the case, I hope it's one of these -- or all of these.)

But, since we're talking about audition cities, it's safe to say that we're talking about a replacement for Simon Cowell. But that's just me -- what do you think?
