His comments are more of an attack against EA than a compliment for Activision, however -- he mentions Call of Duty and Guitar Hero as big franchises for Activision, and they are, but he doesn't say a word about the Blizzard merger at all. And on the EA side, he leaves Rock Band off the list completely (EA is distributing it, not publishing it), and makes no mention at all of Madden or any of EA's other big franchises). Plus, he's been down on EA for a long time.
In short, this isn't going to change anyone's mind. If you're a fan (or stockholder) of Activizzard, then great, there's a bright future in it for you. And if you're not, and you'd rather embrace EA, this guy is just biased enough that he's not going to change your mind. But we're all for competition anyway -- it can be good games time now?
