I guess my question for
@Connorb0t2 and others is why do you believe random text leaks like that? You can go on 4chan or GameFAQs and find half a dozen in a matter of minutes. The only person so far that's seemingly shown any bit of actual knowledge that has actually been officially announced is Vergeben, and that was base game roster and not DLC. (Well besides that Reddit guy who was fired from being a tester and released game mechanics for Inineroar and Piranha Plant months before release.)
Unless I missed something, Verge's last bit of information he's made public essentially amounts to "Minecraft may be represented by a boss, with Steve possibly or possibly not being a character" and that at this moment it's almost impossible to tell what characters he's heard about may or may not be legit. So, nothing really. I think Vergeben, if he says something with certainty, has earned a bit of trust to at least consider, but since he's not committing to anything at this point, I think it's fair to say that we probably shouldn't be believing anything at the moment.
If new information surfaces and has valid evidence, maybe I'll reconsider, but I don't think there's any reason at all to assume any of our current leakers we've seen knows for certainty even one of the characters at this point.
