This Saturday’s upcoming UEFA Champions League Final will pit English Premier League club Chelsea against German Bundesliga club Bayern Munich in a battle for all the European marbles. But another rivalry will be playing out during the commercial break (perhaps an even greater one, if you’re among the 99% of soccer worshipers who wanted to see a Real Madrid-Barcelona clash manifest itself).

EA and Danger Close’s Medal of Honor: Warfighter, along with Activision and Treyarch’s Call of Duty: Black Ops II, will both run brand new trailers during the match. Coverage begins at 2 p.m. Eastern Time on Fox (America) and Sportsnet (Canada), and EA is saying the Warfighter add will air at 2:30 (though that could just be a placeholder for kickoff – halftime is the traditional big-ticket advertising window).

The content of both trailers is still a mystery, but it presents an important opportunity for each company to tweak the narrative heading into E3.

For EA, they’re still the underdog in this dual. The first Medal of Honor modern-military reboot debuted to average reviews in 2010, and was a mere pedestrian in the skyscraper-sized shadow of Black Ops’ record sales numbers. Couple that with EA’s  recent fledgling in the financial sector, and it’s no secret that the future of the franchise is likely hinged on Warfighter’s success.

Medal of Honor Warfighter Trailer Champions League

A Warfighter gameplay trailer did release earlier this April, with Danger Close’s new global focus taking us to the Philippines for an explosive hostage extraction. It gave us brief flashes of the micro-environmental destruction rendered by the Frostbite 2.0 engine, with wood splinters spraying as often as bullets, but it was nothing the hardcore shooter fan hadn’t seen before.

Then again, many might say the same thing about Activision and Call of Duty. There’s no doubt that the futuristic 2025 setting of Black Ops II will take the campaign and its cast of characters (both new and old) to a more aberrant sphere of storytelling – but what does it mean for gameplay? Will Treyarch’s plans for branching storylines and player choice create an experience that feels reborn, not popcorn? Will multiplayer evolve with the time – or try to stand the test of it one more year?

A boundless potential exists for Black Ops II with the resources and development talent being thrown at it, and we wouldn’t be surprised to see a marquee demonstration at E3 similar to last year’s Modern Warfare 3 New York mission. Whatever airs tomorrow might steer us in the direction of what to expect.
