SSX Blur is the only EA Wii exclusive so far, they have stated they have several more (3+) wii exclusives in development. I think EA was suprised how well Madden did on Wii in 6 weeks (200k+ units according to VGCharts) and that's comparable numbers to 4 other 3rd party wii titles, which is better than most companies seemed to expect.
Nobody is crazy enough to accuse me of being sane.
