In his blog post about his departure, he had this to say:
"Beginning early May, I will join Apple as global editorial games manager, App Store. In a nutshell, I will be leading the charge for games on the App Store, so whether you browse through iTunes, iPhone, iPod Touch or iPad, the games content you see will be handpicked and organized by me and my team."
As I posted in a comment on Joystiq's article on it, I've been a long time reader of Matt's work, and I've been perusing IGN ever since it's IGN64 says.
Good luck, Matt. It's a good thing we've got a gamer on the inside. Perhaps you'll be handling my game, whenever that comes to fruition.
Bye IGN, Hello Apple • Mouth on Fire
