Super Smash Bros Announced For Nintendo Switch

During the last Nintendo Direct, Nintendo revealed that a new iteration of Super Smash Bros will be coming to the Nintendo Switch. During the trailer we were shown Mario, Link, and Inklings were shown. Besides those characters, not much else is known about the new game. Is it a new game, or a port of Smash 4? What characters will get gut, and which will get added? We have literally no idea right now. We don't even have a release date yet. Hopefully we get more information at E3 later this year.
