If you wanted any further proof that Christmas is very close - looking at a diary would normally provide the evidence you require - paddypower.com has opened betting for the Christmas video game No.1.

There's no surprise which game is the red hot favourite. After the massive sales of Call of Duty 4, Activision's follow-up, Call of Duty World at War, is odds-on to claims the No.1 position in the All Formats Full Price video game chart compiled by Chart Track for the week ending December 20, 2008.

Offering slightly more generous odds are EA's FIFA 09, PES 2009 and Need for Speed: Undercover. But perhaps the best bets are to be had on a quartet of Nintendo Wii heavy hitters: Wii Fit, Mario Kart Wii, Wii Play and Wii Music. At the time of writing, Wii Fit and Wii Music are at 20-1, Mario Kart Wii is at 40-1 and Wii Play at 50-1.

It's hard to believe any game will manage to topple the all-formats sales of CoD World at War, but those Nintendo prices sure look tempting. You'll find the up to date price list over on paddypower.com.
