User blog comment:Legendary Pop-Fizz/Smash Bros. NX will be a Launch Title! and it was confirmed 2 years ago?!?!/@comment-26824902-20160128185331

I have a feeling it's gonna be an enhanced version. I think it would be way too much work if they made a whole new Smash game after they made Sm4sh. I hope they add more newcomers and stages.
