It's been 21 months (!) since The Sopranos had any new episodes on HBO. They're finally returning tonight for the first part of their final season. So... who will be the first to get killed? Believe it or not, there are actually betting odds on that very topic. The numbers crunchers over at PinnacleSports.com think, of the 18 regular characters, it'll be either Uncle Junior or Christopher. Each have received 13% of all the money wagered. The odds of Uncle Junior biting it are 11/2, while the odds of Tony Soprano's nephew, Christopher, getting killed are 6/1. Tony's sister, Janice, has odds of 11/1. And, it could happen tonight. Newsweek says we'll see "a murder, a suicide, a maiming, a fatal heart attack and a shooting - all in the same episode."

So... care to wager a bet about will be the first to get whacked this season?

HBO understands the viral power of the internet and is apparently hoping to get in on it with a couple of online promotions for the upcoming season of The Sopranos, which starts March 12. First, it's paying Google to use its maps to identify certain parts of New Jersey where key parts of The Sopranos have happened (does that mean we'll know where Ralphie's head is buried?). Starting February 27th, all you'll have to do is go to Google and type in "Sopranos Map".

HBO.com is also planning an interactive game called Whack a Soprano.
