IGN points out that the debut trailer will apparently be aired during the NFL draft on ESPN. Little is known about Call of Duty 4: Modern Warfare at the moment, but the game looks set to transfer combat operations from WWII to the modern battlefields our soldiers face today.
Look for the worldwide debut of the Call of Duty 4: Modern Warfare trailer Saturday, April 28 on ESPN at 10 am Pacific Time / 1 pm Eastern Time during the NFL Draft.
