No retail? Dynasty Warriors 8 came out this week. It's actually getting good reviews online, which says to me that Tecmo Koei has finally started bribing the review sites. The game hasn't changed that much...
Joystiq didn't post any retail releases so I didn't have anything to include. There was probably more stuff across the Nintendo eShops than just Earthbound, too. Not that I've played anything apart from Animal Crossing: New Leaf lately. I caught a scorpion yesterday!
Thread ahead: Animal Crossing: New Leaf Next thread: PS3 releases: week of July 15, 2013 Previous thread: Earthbound! Wii U releases: week of July 15, 2013
To my knowledge, SoCom is the only game out right now that uses a headset, though I'm sure more games will eventually take advantage of those capabilities.
