More official details about Super Smash Bros. for Nintendo Switch will be revealed next month at E3 2018, but that hasn’t stopped fans from sharing all sorts of rumors. One particular fan has supposedly leaked a ton of info, including unconfirmed information about the roster of playable fighters, which apparently includes the return of Ice Climbers, as well as newcomers Simon Belmont from Castlevania and Ridley from Metroid:
I know for sure and from one of my most credible and proven sources (the one who told me about Metroid Prime 4 being developed by Bandai Namco before anyone else said or knew anything about that) is that Ridley is a newcomer, the game is infact a sequel, but there will be assets being reused to some extent(s).
From a different source that I have also known to get things right in the short time that I have known them, there will be the return of Ice Climbers and a new Konami rep…. Simon Belmont. They say that they know that Ridley will be revealed at E3. I was even told by them that everyone is coming back from Super Smash Bros. on Wii U and 3DS. That includes all of the guests. But it otherwise will be a new game. Which I found interesting there will infact be no cuts.
