Third Party Developers have always run under the giant shadow of EA until now. Publisher Activision has swung into 1st spot for the first half of 2007 with stellar game sales, thanks due mainly to stellar sales of Guitar Heroes 2. Facts and figures aside, the question now is will Activision be able to continue this performance into the second half as stiff competition arises from EA with Medal of Honour and new Sport games including the annual million seller Madden.
