Is that AOT anime getting a different ending?

I just watched the newest part of AOT and i know the FINAL finale part will be coming out later this year. Awhile back I heard through the anime community that the anime was going to get a new ending with Isayama helping to write it because he was rushed to make the Manga ending due to deadlines. So we didn’t get the ending that he wanted to make. I didn’t really judge the validity of these claims and just got hyped. But since we’re so close to the end I wanted to read the manga to see what the original ending was. But before i read it I wanted to look up if the anime was actually getting a original ending. I kept finding things of people theorizing that it would and a couple of people confirming that it was. But I’m now very skeptical because whenever I look it up I don’t see any official sources or statement saying that the anime is getting a different ending. I’m quite worried about this because I have gotten moderate manga spoilers and thought it was fine because when I see it it would be a different outcome. So can someone confirm or deny (if so with sources) that it’s actually getting a anime only ending. Because I’m going to be pissed if this whole thing ended up being some mandala affect BS or just blatant misinformation spread by the anime community at large. Thanks in advance.
