Activision is to air a new Call of Duty: Black Ops 2 trailer during this Saturday's Champions League final between Chelsea and Bayern Munich. There's no word on what will be shown but we can expect some futuristic fireworks to keep viewers entertained if they're not stuck at the bar at half-time. It seems unlikely that it'll offer anything other than a cinematic look at the game's campaign, but we can't wait to get our first look at the game's multiplayer component.Activision Publishing CEO Eric Hirshberg said last Wednesday that the publisher is "incredibly pleased" with early Black Ops 2 pre-orders, "which in the first week since reveal are tracking ahead of the record-breaking pace set by Call of Duty: Modern Warfare 3".
