It seems as if we have a some sort of disagreement potential characters by certain leakers. For the time being, we should wait and see.
Verge is the only reliable source so far that we can at least consider more greatly due to what we have seen him accurately show in the past. His sources have been able to at least gain some information in the past about the game, which makes Verge easily the most trustworthy.
MasterOfHyrule is possibly another, being able to leak some information pre E3. However he hasn’t leaked anything since then, so we need to wait and see since we don’t know if his sources knows about Ultimate.
Next is the Senyoujuw?????, and aside from Verge stating that they talked with each other on some sources... there is some statements, most notably a Grandblue charcater joining Smash, that should make this leaker’s statement be taken with a bigger grain of salt.
However, it’s a wait and see for all of them. The reason why I have doubt on some of their statements is that... well... their text leaks. Some are more likely than others, but it’s information being passed down from person to person that they are given. Some could be fabricated by Nintendo even. This also supports why Verge is more trustworthy, in the sense that he has multiple sources to at least justify him passing down information than presumably some of the others who most likely had just one source than have information that can be easily sourced back to the leaker. This sort of information is not as concrete as, let’s say, a picture leak/video leak. We’ve seen with the general consensus that the recent Ken leak is 100% real because it can’t be easily fabricated, and the information is right in front of them. (Pictures leaks can also be easily disproven as well, which is also a plus).
Nintendo’s making sure nothing gets out of hand like last time, which is why I’m looking more into what they have to say with more pessimism to truly believe it.
