Yes, i think it's there.
We know they're not talking about Konoha or their shrine. It's something we're not supposed to know of. I'm thinking that's where Madara has gone, Itachi will already be there and they're getting ready to welcome Sasuke.
Sasuke probably knows of the hideout from the secret scroll of the Uchiha, that's how he obviously knows of Madara. Considering what we know so far, it would make sense for it to be there.
That place is significant in a lot of ways.
Sasuke is being set up to take a fall. So many revelations and there's still more to come.
Anyways, regardless of whether you agree or not, where do you think it could be located?
