Really, this is the best move Sega can make right now. But the best way to be competitive with any EA title (since they now have exclusive rights to the ESPN brand) is to make a deal with Fox Sports, who has cemented itself as the world's baseball leader. (Although the idea of a video game Joe Buck might sicken more than a few)
The best part of the article for me? Take Two is paying for this potential deal with profits from GTA!
As for the "Meat," it seems like every other expansion has made a significant change to the gameplay or player options. Burning Crusade: New zone, flying mounts, two new races, Horde Paladins, Alliance Shaman, the new continent, 10 levels.
