It might be an exercise in stating the obvious but recent shots posted by Game Informer magazine show the massive graphical gulf between the Wii version of Call of Duty 4: Modern Warfare - subtitled "Reflex" - and the original PS3/360 instalments, on which the game is based.
Still, if the developers can carry across the killer gameplay then such visuals issues won't present a problem.
Multiplayer fans will be pleased to know that Reflex will feature 10-player online, although the voice support seen in the 2007 original is missing.
The game hits store shelves on the 10th November, around the same time that the 360/PS3 sequel is being released.
UPDATE: Nintendo Life member Shiryu has pointed out that some kind of voice chat IS being promised for the Wii version, as is shown in this image.
