While predictions tend not to be 100% accurate, especially my own (so take this list with a grain of salt), I'd like to at least try giving an educated guess as to what the tier list may turn out to be (if not closely resemble) in the future of Smash 4. I'm at least going to try to give my educated guess based on the buffs and nerfs of characters, as well as possibilities of potential and MU changes. But as a disclaimer, I do not want to derail the topic; instead, I'll attempt to not only keep this tier list on here, but I will also attempt to not derail even with this list prediction:
Tier predictions are technically on-topic right now aside from combos and character viability traits being shifted. Characters who have gained significant buffs, like the bottoms who were buffed, are going to see some tournament representation hopefully, with Samus possibly going into mid-tier due to her significantly boosted MUs against characters she would have once went even or slightly struggled against, as she is more versatile than ever before.
Sadly, I guess I even think Jigglypuff is the worst character, since her MUs have only become nerfed thanks to characters like Ganondorf being buffed overall, making it almost impossible for Puff to really win.
As for some of the placements, I actually did see many peoples' posts about their own opinions and formulated that alongside my own thoughts. Cloud, however, I firmly believe to be only one placement down. Yes, he's still a versatile character and some of his MUs have been toned down, but some of his other MUs, especially Samus, have also taken turns for his disadvantage. Plus, having Finishing Touch not able to kill opponents jankly low in mid-air is more of a nerf that is very harmful to him, and all of the nerfs he received makes him just worse, not better. Even with better MUs against some characters, there are more characters that now have advantages over him, thus causing him to be lower in my own prediction.
I'm sorry, but I'm not buying the Cloud hype whatsoever, and I honestly think everyone's over-estimating him.
Funny coming from a guy who plays Cloud himself at a very decent degree.
(One can say I at least TRIED to not do anything bad. And talking about tiers isn't derailing the thread, since we're already talking about them.)
