Yesterday Nintendo announced the latest in their line of Nintendo Directs focused on upcoming Wii U titles; and Bayonetta 2 is the star of the show, this time!
The direct is scheduled for 3PM PST (6PM EST) this Thursday, and the duration of the broadcast has yet to be announced. Nintendo also previously held Nintendo Directs for other specific Wii U titles - Including Platinum Games' own The Wonderful 101, and Tecmo-Koei's upcoming Hyrule Warriors - both titles that Nintendo has been involved in publishing and marketing, much like they have been for Bayonetta 2.
Information that individuals may expect might be related to announcements made for the title at E3 - such as the Bayo-Mecha combat, the Online Multiplayer, and the enhanced edition of the first game that comes with the purchase! Beyond that, like the other game-specific Nintendo Directs mentioned, you should expect some form of developer commentary alongside any new announcements and gameplay modes (Bloody Palace, anyone?) and features.
Bayonetta 2 is scheduled to release on October 24th.
