EA could make the Wii Madden look realistic if they wanted to. Just look at Madden 07-08 for Wii. Both have the PS2 type look. But EA chose to cater exclusively to casual gamers for Wii version of Madden, thus the cartoony look for the past few versions. Disappoints me that they took that direction, but it is what it is. I know plenty of people that would be interested in Wii Madden if not for that kiddish look it has.
EDIT: Does anyone else notice the scoreboard in the Eli screenshot looks a LOT like CBS' scoreboard for NFL? Maybe I'm reading too much into it, but that could add to speculation of Network Presentation.
