Super Smash Bros 4 is expected to be discussed at the upcoming E3 2014 gaming conference, leaving many fans wondering if the highly-anticipated Wii U and Nintendo 3Ds game's release date gameplay will be shown in a trailer leak.

"We know the title will be out this summer on 3DS, and most likely this winter on Wii U, but it's seeming increasingly likely that we'll have to wait for this June's E3 for the exact release date," GamenGuide.com writes.

"What we will consistently see are daily updates from Nintendo on the game's official site. The last significant info drop came from a Nintendo Direct, below, which revealed several new characters and details. While the daily posts don't give as many details as that video did, rest assured that series director Masahiro Sakurai will continue to post some form of content from the upcoming titles to appease fans."

Super Smash Bros 4 is expected to be one of the more releases for the Wii U and Nintendo 3DS consoles, which have been trailing behind the Xbox One and Playstation 4 in sales.
