As is in any sports game, it's all about the branding. "NFL" is obviously going to sell more than "CFL", for example.
In MMA, the big dog is the UFC. Their videogame is selling like hotcakes. But in this sport, there are many players in the game that have potential to dominate the market in the future, unlike in other sports where there's always a clear leader and there are no actual competitors (like NBA, MLB, NFL, NHL, etc).
Now EA seems like it's set to grab pretty much every other fighter that is not signed with the UFC. Some points to consider:
1.) EA has already signed arguably the best fighter in the world in Fedor Emelianenko. Basically, all the hardcore American fans are gonna buy this game because of this, which is a substantial number. Fedor is also a superstar in Europe and Japan, where the game could be huge.
2.) EA also has already signed the most popular fighter in the world in Randy Couture due to a contractual dispute with the UFC from last year. If he's placed on the cover, this could be huge in America. After all, Randy is Captain America.
3.) The UFC game has 0 big name asian fighters (specifically Japanese fighters). MMA, though, is absolutely huge in Japan, with some huge stars potentially available to sign with EA.
4.) "MMA" is nowadays synonymous with "UFC". This could be a good thing for EA as well, especially if Randy is on the cover, because everyone who watches the UFC knows Randy. Casuals might come to expect UFC fighters in this game and buy impulsively.
5.) The problem is there's not much else aside from these potential markets. Dana White has already stated that no UFC fighters will be allowed to sign with EA, and UFC fighters have twice the exposure of those outside of it. The competition from outside the UFC has plenty of talented fighters, but none are quite as marketable.
I personally think that this game can match the UFC game's success, though of course it won't outsell it by any means. It will probably make 70-80% of Undisputed's sales.
