Kotaku has posted an article featuring another interview with new EA Sports Football GM Cam Weber discussing Madden NFL 12 and beyond.
"Weber showed up in February, halfway through Madden 12's build. What a three-year plan is, Weber says, is a comprehensive focus on football gameplay - "whistle to whistle" as he says - that's meant to keep each year from being purely reactive, so that future editions going forward all have identifiable long-term development behind them. In so doing, he offered that Tiburon's core football gameplay team would double in size. Though this crew works on the engine used by both Madden and NCAA, that became "Madden's team is doubling."
Weber reiterates: Twice as many people will be working on core gameplay for both games. Madden and NCAA retain their own teams of designers, producers and animators, focusing on the features that differentiate them."
