Sony stepped up its rhetoric against Apple at its E3 keynote today with the start of a new ad campaign. The new spots, centering around a teen named Marcus, argue that the PSP hasn't been getting enough attention and that it deserves more credit as a game system. In one ad, he complains to Sony exec Kevin Butler that he's tired of people "talking about those apps on the phone" in an obvious poke at the iPhone, suggesting the attention should go back to games such as Peace Walker.
