When I first heard about this story, I was thinking that Medal of Honor was just following Call of Duty footsteps. The only way I can see it standing out if it continues the series historical accuracy angle instead of Call of Duty's blockbuster style.
i don't think it's going to be a bad game, i don't have a problem with the premise of the game, in fact i think its pretty baddass. but the only big problem is the fact that (as leo mentioned) it's going to be compared to modern warfare. and if medal of honor wants to stand a chance, they'll have to focus on the historical accuracy as well as take advantage of the modern setting and the war itself, to introduce new elements in the game. if they're ballsey enough, they may even inculde suicide bombers.
Comparisions between the new Medal of Honor and MW2 are inevitable, and EA picked a shitty time to come out with this game seeing as most people will see it was a MW2 rip off. If they want this game to make money they're going to have to seriously sell this as a different experience to the gaming community, and odds are that the game is going to be rated T for teen and I don't know why, but that's a turn off for a lot of gamers, especially FPS fans.
