This pre-E3 Direct is likely this year's version of Nintendo's traditional press conference.

A Wii U focused Nintendo Direct presentation will be taking place on June 11th at 7 a.m PDT (10 a.m. EDT, 3 p.m UK time). This Nintendo Direct has currently been announced for North America and Europe with each region airing the event from their own Nintendo Direct website. It’s currently unknown if the information will be different on the region specific streams.
The Wii U focused Nintendo Direct takes place only five hours before the E3 show floor opens to attendees, and only three-and-a-half hours before Nintendo’s pre-E3 Wii U Software Showcase admits select members of the press into the Nintendo booth to get hands on time before the big crowds are let in.
This presentation is most likely what Nintendo will be using to showcase their big E3 games and announcements instead of their usual press conference. The format of a Nintendo Direct followed by a media-attended "Software Showcase"is not unprecedented: Nintendo executed a similar chain of events focused on the 3DS on April 17 of this year.
I really hope that the rumors are true and in the Nintendo Direct they announce an eShop version of Xenoblade.
Oh boy another year of no F-ZeroNever give up! We'll get one eventually!
