Yup.
That quote...
""I know the fans really want The Last of Us Part III---I hear about it all the time---and all I can say is that we're already into our next project. So the decision has already been made. I can't say what it is, but that's the process we went through---that there was a lot of consideration of different things, and we picked the thing we're most excited for.""
So the project they picked to work on next, that they are most excited for, could obviously be TLOU PT3
I'll be honest tho, after TLOU PT2, they really need to have a story that makes you like the characters again. There needs to be some sort of redemption arc after the non-stop savagery tone of TLOU2.
It also needs to be more than a linear third person shooter walk and talk slog. Broaden the world building, gameplay mechanics, character progression so that it isn't intentionally sabotaged by a split game.
Otherwise? If it's structured as more of the same like TLOU2 was, I am not particularly excited for the project.
