Nintendo opted out of a big press conference at E3 this year, but they will host a Nintendo Direct on June 11 (7:00am local time, 3:00pm BST), and for all intents and purposes the one hour broadcast is likely to contain close to the same amount of news and announcement as you'd expect from a press conference.
Platinum Games' Hideki Kamiya confirmed on Twitter that Bayonetta 2 will be part of the Nintendo Direct broadcast. Rumours circulate that we'll get to see the next Mario Kart, a new Zelda and a Mario 3D title as well.
