User blog comment:The shy platypi/Super Smash Bros. Wii U/3DS' Final Presentation/@comment-26399637-20151209191416/@comment-6684591-20151209193603

I'd be content if at least Inklings were added; frankly I'd be surprised if they weren't. They are a popular choice in the Ballot in both Japan and the rest of the world and Splatoon is a big Wii U seller, so putting Inklings in Smash would not only make a lot of people happy but would be a good business decision by Nintendo.
