Peter Moore with EA recently stated that they have no further games coming to Wii U, so they have essentially abandoned the platform. Its never good to lose support of a top publisher, but does this give other publishers an opportunity to capitalize on the platform. For example, Acclaim has a lot of success on the N64 with NFL Quarterback Club, All Star Baseball, and NHL Breakaway. Acclaim was more success than EA on the platform with their sports titles even though EA's titles were more popular accross all platforms. EA brought lackluster efforts to the N64, and Acclaim was there with their sports titles top clean house. Not only that, but Acclaim started up the highly successful Turok series on the N64. Acclaim had huge success on the N64.
I think EA's support should be a green flag for other publishers to take advantage. If EA isnt going ot support the Wii U with sports titles, then that leaves the door wide open for someone else to capture the market. Seriously, they could end up with zero compeition for sports games on the Wii U if EA doesnt support the Wii U.
There are definately gaps to fill with the absense of EA, but if I were Nintendo, I would be working hard with other publishers and developers to fill those gaps rather than begging EA to come back with their half hearted ports.
