Rosie is going nowhere. She's simply the next A-list Mario rep because of how popular she has been since Galaxy. Wii Fit probably isn't leaving because of the Rob/G&W trend.
The key here is that there probably won't be a Smash 5 for another seven years. They're going to port Smash U/3DS over and add four or five characters and make Smash Bros. For NX. With a year or two max left before launch and Nintendo KNOWING they need a home run launch for real this time, there's no way they're going to start fresh on a Smash game and have it ready without delay.
So if we get a PROPER Smash 5 on their 10th gen platform, yeah, I can see Cloud getting cut by then, and probably Bayo along with the clones. Other than that, though? We're probably just gonna have them all stay. Maybe Ike goes because Roy is back for good, maybe they cut Robin or Corrin for the next Fire Emblem character of the month, etc., but looking at how Sakurai got all of this done in two years (minus the DLC characters), I can't see him ever going back on that. The only two cut characters left are Pichu and Wolf; Wolf could easily be back in Smash 5, Pichu is gone for good because joke. ICs are likely back for Smash NX next year.
All of that said, you can never be sure with Sakurai. Unless it's more FE characters, then apparently you can be.
You should check out my YouTube channel, The Golden Bolt! I review all types of video games, both classic and modern, and I also give short flyover reviews of the free games each month on PlayStation Plus to tell you if they're worth downloading. After all, the games may be free, but your time is valuable!
