Who's the Favorite to Win Season 10 of dancing with the Stars?

I came across the odds for who will win Season 10 of Dancing with the Stars.  It only covers the professionals of course, as the celebrities have not yet been announced.

It was an interesting list as so much depends on the celebrity and you have to imagine all the professionals have the same partner (gender aside).  Here's the list:

• Derek Hough +600
• Mark Ballas +700
• Julianne Hough +750
• Cheryl Burke +800
• Maksim Chmerkovskiy +800
• Lacey Schwimmer +800
• Chelsea Hightower +1000
• Dmitry Chaplin +1200
• Karina Smirnoff +1400
• Kym Johnson +1400
• Alec Mazo +1600
• Louis van Amstel +1800
• Edyta Sliwinska +1800
• Anna Demidova +2000
• Tony Dovolani +2500
• Anna Trebunskaya +2800
• Jonathan Roberts +3000
• Ashly DelGrosso +3300
• Elena Grinenko +4500
• Inna Brayer +4500
• Corky Ballas +6600

(Example: If you bet $100 on Derek Hough and he wins you get $600 plus the original $100.  If he loses you get nothing!)

Some thoughts:

• Derek and Mark deserve to be at the top given their track record and their popularity
• While she does deserve to be one of the favorites, Julianne has not even confirmed she will participate in season 10!  (Or I've missed something?)
• Given so much depends on the celebrity, I am a little surprised at how wide the range of the odds are.  I don't think Tony, Anna T and Jonathon deserve such long odds...perhaps worth a flutter?

What do you think?
