Michael Rawlinson, managing director of ELSPA, said: "Christmas 2008 will be yet another great year for video games and we are all dying to know which of the amazing front runners this Christmas will make it to No1.

There are, as always, a remarkable array of competitors for the number one slot and it is impossible to tell if the favourite will make it or be pipped to the post".

However Ladbrokes' spokesman, Nick Weinberg, thinks the winner is more certain than that. He said: "The battle for Christmas supremacy gets bigger and better each year. It's now a staple part of our festive betting diet. Call of Duty is the field's stand out favourite. It's going to take a monumental effort to wrest the gong from the market leader's hands".
